I've been through hurricanes, floods and massive floods, bad storms, and even though hills and mountains surrounding us, we've had destructive tornadoes of all things.
Through all these things I learned to be what I've affectionately call being "a casual prepper".
Generally canned food last 1yr, a year and a half, or two years or even longer.
Then there's MREs, I think they last at least 10years, come with a chemical heater pack.
Then there's 25year shelf life freeze dried meals, just add water.
After major flooding in '05, '06, '11 which left us without electric power for a minimum of 8 days, and longer. That was due to the power substation itself was in the floodplain. We ourselves had no water up where we were, but canned food cooked over a small propane stove Allowed us to eat, because I can tell you dry ice, even when delivered in the morning by the fire department, and again in the evening by a do-gooder girl scout trying to earn some kind of "community service" badge will NOT keep a freezer frozen!
I learned to shop for just one or two cans of soup, veggies, fruit, stew, chili, etc every week when I shopped to add to "back stock", to "prep" for next loss.
I also pick up things in boxes...like pasta, boxed meals, etc.
I actually learned that after a hurricane. Because I was down to eating a cold can of green beans or a cold can of ravioli the last day the power was out, as I didn't keep much on hand, and my night job was as a line cook in a 4 star restaurant.had the power not come back on that night, I would have been out of things to eat, and as it was I had to eat them cold, as I had electric stove too.
( Later being homeless I would re-experience eat cold stuff out of cans!)
Buying just one or two extra of something every time you shop, or buying MREs or Freeze dried meals on sale on occasion, WONT bust the budget, and one will develop a "back stock" of their own.
Also, when we are down, about half a supply of ANYTHING, I buy a fresh new supply.
Example: when 4 of the 8 rolls of TP are gone, I buy a new package, I don't wait till the very last one is on the wall holder, I buy then. Rinse and repeat. Next time I should have a few rolls from the first PKG, and a few rolls from second PKG, when I go to buy a third.
I build up back stock, don't break the bank, and don't need to"panic buy" when an event happens.
I recently started purchasing the limit of canned goods ( limit 4) while they are now still $0.49 a can at Aldi's, because I DO believe the farmers are right: there will be a shortage, and thusly prices will go up. I may only need to buy 2 cans, but an extra $1 won't hurt my budget and I'm two can ahead in backstock.
I even buy canned chicken, beef and pork.
Ive got propane.. enough for cooking for a while, and I don't rely on refrigerator/freezer electric products to keep my food.
I also have all the equipment to dehydrate and home can foods for use later.
Best thing of all, IS if there is no rising cost, or shortage, I certainly wouldn't have to buy food, oh for a year or two, and not really skip a meal.
You can call it prepping, or hoarding, or stockpiling, but I call it smart. I've learned from being without.
So this household will last quite a while, with self contained portable potty, 48 current count of TP, and blue sewage destroyer, 60# of propane for heat/cooking, plenty of food, and 2 gross of 4 hr. Tea lights, and a gross of 6 hour tea lights, and plenty of 8 hour votives to keep light at darker hours. Tea lights are also meant to do what? Keep tea warm or melt smelly wax, and thusly they will raise the temp of a 12'x12' room! 4 will do just fine to raise the temp about 10-15°.
Next "prepping supplies? SOLAR PANELS AND A SOLAR "POWER GENERATOR INVERTER'.
GOTTA READ up on that, to then carefully buy what I need. A more expensive proposal than just buying"one or two" extra food stuffs, but will run a fridge, lights, even smaller AC, OR smaller electric heater s!!!
Best to all, I just use Positive future thinking!
