09:04 – Thirteen days left until the election. Even if you don’t really expect anything catastrophically bad to happen–I don’t–it’s only prudent to be prepared for violent civil unrest, even if it’s only localized. It may be your local area that’s affected. Particularly if you’re in an urban environment, stay away from crowds. If I worked in a large city, I’d go as far as taking a vacation day and staying home from work that day. Just ask some of the people from Charlotte, who didn’t realize that they were driving into a life-threatening situation. And be aware that the worst danger of civil unrest won’t necessarily be on Election Day itself. It may be on the following day or the following several days.

If you’re not at all prepared, there’s still time. Make a Costco/Sam’s/Walmart/supermarket run. Pick up several cases of bottled water, at least one or two cases for each family member. Pick up enough shelf-stable canned and dry foods to last you at least a week. Two weeks would be better. Buy foods that require little or no preparation. If you don’t already have them, pick up some LED flashlights/headlamps/lanterns, batteries for them, and a battery-powered radio. Buy a Coleman dual-fuel camp stove and a couple of gallons of Coleman fuel for it. Make sure your cell phone is charged, and charge the extra battery for it, if you have one. Refill any prescription medications that you’re down to less than a month’s supply of. If you don’t own a firearm, buy one now, along with at least 100 rounds of ammunition for it. A short-barrel pump-action shotgun is a good choice for most people, but even a .22 rimfire rifle is a whole lot better than nothing. Fill the gas tank(s) of your vehicle(s). If you have a propane grill, make sure the tank is full or nearly so. Buy an extra tank. Keep as much cash on hand as you can afford, mostly in small bills with at least several dollars in change. If you live in a densely-populated area, be prepared to get out of town if necessary. Keep your food and other emergency supplies in or near your vehicle, and make arrangements with family or friends in a more lightly-populated area to visit them if things go downhill in your area. Tune your radio to a local station, and keep an ear on it. And if violence breaks out in your area, be prepared to evacuate on a moment’s notice. Don’t wait around to see if things get better. They may, but they may also get a whole lot worse, stranding you and your family in a dangerous situation.

More work today on science kit stuff and repackaging the remaining bulk staples we have sitting in bags.

09:45 – With regard to non-prescription antibiotics, as of January 1, 2017 the FDA is transitioning many standard livestock antibiotics from OTC status to what amounts to prescription status. If you want to get some antibiotics, you might want to do it right now. See The End of OTC Veterinary Antibiotics and this PDF link.

We include small amounts of several livestock antibiotics in our biology kits, including penicillin G potassium, oxytetracycline, and sulfadimethoxine, all of which will be restricted as of the first of January. I plan to stock up on those before the deadline. I’m not sure what effect these new regulations will have, if any, on “fish antibiotics” like those sold by aquabiotics.net, but it’s probably safer to assume the worst.

If you need guns, ammunition, or high-capacity magazines, now would also be a good time to get them. As in past panics, if Clinton is elected you can expect extreme shortages and prices that may double or triple overnight.

Barbara is volunteering at the library this evening for the Quiz Bowl. We’ll have an early dinner, and then it’ll be wild women and parties for Colin and me until Barbara returns later this evening.

08:11 – Barbara and I didn’t bother watching the debate last night. Same old, same old. Instead, we watched The Walking Dead and the 1971 version of Upstairs, Downstairs.

We have science kit stuff to work on today as well as a couple minor things to get done on the LTS food storage.


14:21 – We just got back from a run down to Winston. Barbara and I both had dentist appointments. Afterward, we made a small Costco run. Not even enough to fill up the way-back of her compact car.

09:17 – Barbara was out doing some work in the yard yesterday when she was attacked by our black walnut tree. The winds were gusty, and walnuts started dropping in droves. At least one nailed her. There are hundreds of them down in the yard now, with hundreds still remaining on the tree.

I’d like to harvest the walnuts, but I have no idea what the best way to proceed is. I vaguely remember back in the 70’s visiting a friend of a friend who had walnuts. IIRC, he’d collected them and put them out to dry. He had a steel plate with walnut-size holes in it. After filling the plate with raw walnuts, he’d smack each one with a rubber mallet to drive it through the hole and de-shell it. But we have no such plate, and I’m wondering if there’s an easier way to go about harvesting them.

Barbara’s at the gym right now. When she gets back, we need to build another batch of the CK01B chemistry kits. Once that’s complete, I’d like to get more bulk staples repackaged, including several 50-pound bags of flour, sugar, and rice. Also, Barbara has commented a couple of times now that the one-gallon jugs of pancake syrup are awkward to handle, particularly when they’re nearly full. I have several of the flip-top 89 fluid ounce (2.63L) orange juice jugs that we’ve cleaned and dried, so I’m going to transfer pancake syrup from the one-gallon jugs into those. Once cleaned, those one-gallon jugs will be useful for storing bulk staples.

I didn’t bother watching any of the debate last night. Watching two psychopaths going at each other isn’t my idea of a good time. Unless, as I’ve suggested, they arm both of them with helmets, shields, and short swords and let them go at it that way. I think Trump could take her. Not that it’d make much difference. Whichever one wins, we Normals are screwed.

10:25 – The effects of the hurricane are mostly gone up here, other than a stiff breeze with strong gusts. The temperature this morning was in the mid-40’s (~ 7C), but the wind chill was down below freezing. I don’t worry too much about wind unless I see cows rolling by in the field behind us.

We filled bottles yesterday of things we’re short of. Six dozen each 15 mL bottles of barium nitrate solution and potassium ferricyanide solution, and four 3,000 mL bottles of bread flour. Those last were some leftover bread flour we’d packaged temporarily in gallon ziplock bags when we ran out of clean PET bottles. I wanted to get them transferred to a better LTS container, and 3-liter bottles fit the bill. Using a cut-off 2-liter bottle as a large wide-mouth funnel made it easy to transfer the flour. It took only about a fifth as long to make the transfer to 3-liter bottles as it would have taken transferring it to narrower-mouth 2-liter bottles. At some point soon, we need to get another 250 pounds of flour, rice, and sugar transferred to PET bottles. We’ll use 2-liter bottles for the latter two, which are free-flowing enough that the 2-liter bottles work fine.

It appears that the gloves have come off in the Trump/Clinton war of words. I suspect Clinton will lose this battle. She’s an incredibly nasty piece of work, but she’s not the street-fighter that Trump is. Clinton releases a pretty innocuous audio tape and claims that Trump is anti-woman. Trump responds by hauling out the big guns, and accuses her husband of being a literal rapist, with testimony to back that from some of the women who accuse Bill of raping them. So Trump is proven to be crude, which all of his supporters already knew. And Clinton is accused of not just enabling but actively assisting her husband in raping multiple women, which all of Clinton’s supporters also already knew. But I suspect Trump hammering on this is going to damage Clinton by making many of her female supporters think again about the role she played in her husband’s despicable and criminal behavior.

With a month until the election, I suspect that things are going to get a lot nastier. A lot. Given the Clintons’ alleged habit of murdering opponents, if I were Trump I’d be hiring a phalanx of steely-eyed security men who were beholden only to me. And I wouldn’t eat or drink anything that had been out of my sight.

09:40 – Barbara is down in Winston today, running errands and having lunch with a friend. As usual when she’s gone, it’s wild women and parties for Colin and me.

Most people really are stupid. I was just reading an article about Hurricane Matthew, the strongest storm to affect Florida in more than a decade. As usual, everyone panics and heads for the supermarkets and hardware stores to lay in supplies. One stupid woman who was interviewed had gone to her local Publix supermarket, in search of bottled water. She was upset to find that they were sold out of the store brand stuff and had only the more expensive name-brand bottled water left in stock. The article wasn’t clear about her actions, other than that for some reason she lay down on the empty shelf where the cheaper bottled water had been. Presumably, she left without any bottled water because it cost a few cents a bottle more than the house-brand stuff. Jesus wept.

As is usual this time of year, my component inventory system has completely broken down. The problem, as always, is that we’re doing so many things at once, and updating component inventory is often overlooked. For example, we’ll be running short of biology kits and are out of chemical bags for them. So I check inventory and find out that we have only eighteen bottles in stock of the limiting chemical. So we build 18 of the chemical bags and start assembling more biology kits. Meanwhile, we get a bulk order for chemistry kits. We ship those and realize that we’re now short on chemical bags for those kits. So we check our inventory and see that it shows that we should have 27 of the limiting chemical for those kits. But it turns out that another chemical is really the limiting chemical because I hadn’t updated the inventory records after we used 18 bottles of it to make up biology chemical bags. It turns out that instead of having enough to make up 27 chemistry kit chemical bags, we actually have only 11 of that second chemical. So we make up 11 chemistry chemical bags and start building kits. As Barbara is assembling those, I make up the solution for the chemical bottles we’d run out of. So it’s really a matter of us having so many things going on at the same time that stuff slips through the cracks. Multiply that confusion by the scores of different chemicals included in the various kits, with significant overlap between types of kits, and things quickly turn chaotic. Fortunately, things have now settled down to a dull roar, so we’ll have time to rectify the inventory count again by physically counting all of our component inventory SKUs.

With Barbara away for the day, I’m going to spend some time washing and sanitizing bottles that will contain bulk staples. I wish Coke were still sold in 3-liter bottles, because their wider mouths mean they’re immensely better than 2-liter bottles for repackaging LTS bulk foods. Someone mentioned that dollar stores still carry off-brand soft drinks in 3-liter bottles. I may pick up a couple of those to try, because I’d really like to have more 3-liter bottles. I much prefer them to foil-laminate Mylar bags for LTS food storage.

In fact, nearly all of our repackaged LTS food is in PET bottles. We use them for just about everything other than bulk storage of oxygen absorbers, for which we use glass canning jars.


11:32 – Ooh. Almost a prepper fail.

I just started a load of laundry, darks and towels. We use Chlorox II rather than chlorine bleach. When we moved up here, we knew nothing at all about septic tank care, and I decided not to risk killing the beneficial bacteria in the septic tank by using chlorine bleach. Granted, I’d only be using a cup (250 mL) or so a week, but chlorine bleach is an extremely effective bacteria killer. In retrospect, I suppose I should have run the numbers. Assuming a 1,500 gallon septic tank, I’d be adding 1/16 of a gallon of bleach, or one part 5% hypochlorite bleach to 24,000 parts water, assuming the tank is full. Call it maybe 2 ppm. Not enough to kill many bacteria, but probably enough to make them feel unwell.

I have another load of laundry queued up. All of our whites, none of which have been washed with chlorine bleach since last November. Chlorine-free bleach just doesn’t cut it for whites. All of our white underwear, socks, t-shirts, etc. are starting to have a faint yellow cast, which is what happens when you don’t use real bleach on them. So, since I was going to use a mixture of dishwashing liquid and chlorine bleach in the kitchen sinks to wash and sanitize 3-liter bottles, I went off in search of the chlorine bleach. I couldn’t find it anywhere. It wasn’t on the laundry room shelves. It wasn’t under the kitchen sink, where Barbara used to keep a supply of it for sanitizing work surfaces. It wasn’t under the sinks in any of the bathrooms. It wasn’t downstairs anywhere, including in the unfinished area.

I have enough calcium hypochlorite (pool shock) stored with the prepping supplies to make up about 30 gallons of bleach, but I didn’t want to open it. I was actually considering walking down to the convenience store across the road to buy some, but I thought to look in the cabinet under the laundry room sink. Sure enough, there was an unopened gallon of chlorine bleach nestled behind a bunch of 2-liter bottles filled with water.

The takeaway here is that if you don’t know where something is stored, you don’t have actually have it even if it’s listed in your inventory records.

10:00 – We’re continuing to get a flurry of kit orders. As of this morning, we’ve already done 80% of the revenue we did in all of October 2015. I don’t worry about sales numbers too much. We’ll probably end up having a record for October this year, but on the other hand we could end up not selling a single kit for the rest of the month. Things even out, so I don’t worry about it.

We didn’t expect to get much done today because the guys showed up this morning to start pouring concrete. They tell me it’s going to take almost 50 yards (~ 38 cubic meters) to do the driveway, so we’ll have several concrete mixers showing up. The second one is pouring its load as I write this. We expected Colin to be barking berserkly all day long at all the activity out front. He did bark when the guys showed up, but then he apparently decided that if they were okay with us he didn’t need to bark constantly at them. That’s a first for him.

Like everyone, I can think back to things I thought about doing, didn’t do, and later regretted not doing. The one that immediately comes to mind for me was 25 years ago or so, when Barbara and I were in a Walmart and I noticed a stack of crates of SKS carbines in cosmoline and cans of 7.62×39 ball ammunition for them. The carbines were $29.95 each, as were the ammo cans. Three cents a round. At the time, standing there looking at the stacks, I thought seriously about buying a hundred carbines and a hundred cans of ammunition for them. That would have been $6,000 total, and those items would be worth at least ten times that much now. But I didn’t even mention it to Barbara, because I knew she’d freak at the idea of buying a hundred military rifles and a hundred thousand rounds of ammunition. So I walked out without buying even one. I wish now that I’d bought at least a crate of each, if not the whole pile.

Don’t let that happen to you. I don’t really expect anything catastrophically bad to happen over the next few months, but I wouldn’t be surprised if something did happen. Things are really on edge right now, and it wouldn’t take much of a spark to set off the powder keg. If you haven’t done so already, making at least minimal preparations for bad times should be a high priority. If things do turn to shit, you really don’t want to be sitting there wishing you’d bought and done things that are no longer options for you.

09:44 – Last month was really slow for kit sales. The first half of the month was normal for September, or a bit better. Around the 15th, sales fell off a cliff and we ended up doing only about two-thirds the revenue of September 2015. On the other hand, this month is starting out well. We’ve already done a third of the revenue that we did in October 2015.

According to one of my correspondents who wishes to remain anonymous, we may be in for an exciting next three months or so. Apparently, the federal government has warned federal and state LE agencies that there’s a significantly increased probability of widespread violent civil unrest associated with the election, only about five weeks from now, and we can expect an increase in so-called lone wolf terrorist attacks, particularly from Thanksgiving and Black Friday though the New Year celebrations. Intuitively, that makes sense to me. As always, it will be a very good idea to avoid central cities, shopping malls, sporting events, and any other venues that draw large crowds. And, if has been speculated, hackers attack and disable the EBT servers immediately before the election, all bets are off. It’d be a very good idea to have made at least minimal water, food, and defensive preparations, just in case.

10:36 – More kit stuff today, although things are slowing down, as they always do this time of year. We’ll have a couple of quiet months before things start to ramp up again for the Christmas season and the start of the new semester in January.

Autumn is definitely starting to arrive up here in the mountains. The leaves are gradually starting to change and fall, and the nighttime lows are into the low 50’s F (~11C). Mornings are usually quite foggy.

As I’m re-ordering inventory for science kits, it again strikes me how useful many of these items are in a prepping sense. Antibiotics and heirloom seeds for biology kits, raw chemicals that can also be used for everything from making up oral rehydration salts to 131 mg/mL potassium iodide solution, bottles and plastic bags by the thousands, and so on. I’d actually considered making up kits of useful items like ORS components, KI solution, etc., but we’re not certified by the FDA for packaging items for human consumption. I suppose I could offer items for educational laboratory use only (wink-wink), but it seems simpler just to tell people what to order themselves. Most of it is available in reasonably small quantities on Amazon.com, such as this, this, this, this, and, for radiation emergencies, even this.

Or you could simply buy ORS packets, although they’ll cost you about a buck per liter versus a small fraction of that for making them up yourself, and KI tablets, although again those’ll cost you about $0.50 per dose versus about $0.02 per dose just buying 100 grams of KI.

Which brings up the issue of how many doses of different things you need to stock. If you need ORS, you need it badly, and a course of treatment for one person can require 20 to 50 liters, or more. I do keep a 15-pack of the commercial ORS on hand, but those are for if we need it RIGHT NOW. In terms of raw materials for ORS, our inventory varies, but all of the components are also science-kit inventory items, so we typically have 1,000+ liters’ worth on hand. KI is also a science kit inventory item, so we generally have at least 8,000 to 10,000 doses on hand. The latter would obviously be excessive if we weren’t stocking it mainly for science kits, but the former is actually a reasonable level, enough for 20 to 50 courses of treatment.

06:48 – When I was making up solutions for forensic kits yesterday, one of them required concentrated sulfuric acid, 160 mL of it. I always weigh sulfuric acid rather than measure it volumetrically, so instead of putting 160 mL into a graduated cylinder, I put 294.4 grams of it into a tared beaker.

As I was doing that, it struck me that my failing memory is something I need to take into account. I of course remembered that the density of the acid was 1.84 grams per mL. I’ve known that since I was about 12 years old, along with the densities, freezing points, and other key physical characteristics of hundreds of chemicals. Maybe thousands. At any rate, of any chemical I’d ever looked up even once. I should say, I “knew”, since those tens of thousands of factoids that used to reside in my memory have apparently taken the last train for the coast.

Yes, it’s easy enough to look up the density of sulfuric acid on Wikipedia, but what if Wikipedia is no longer accessible? In this case, it wouldn’t have been a problem, because I have a copy of the CRC handbook on the shelves downstairs. But what about all the stuff I used to know from memory I no longer remember? I need printed copies of that type of information. Either that, or a hypnotist who’s good at recovering lost memories.
