Hunt, fish, barter, and can food. There was a run on canning lids awhile back, I bought a re-supply on e-bay. Now who would think there would be a shortage of pressure cooking supplies ? Canned food , pickled, smoked , naturally dried, can all be done without electricity all you really need is water and we're on our own well and a good supply of wood. The other thing is bring back bartering what do you think they did in the depression and farther back. The farmers are the ones that had food on the table. My family sold or traded eggs, made bread, had huge veggie gardens, grew wheat, raised chicken, hogs, sheep, cattle, a few horses and they canned almost everything including fish. In fact I've been getting back into canning fish , peaches, apple sauce , plums, and meats. 65 qts approx for a cow elk that's not including the backstraps and the burger we usually get anywhere from 60 to 100 pounds of burger depending on size of the cow and any blood shot meat. 3 small trout per pint tastes like a slightly rich canned salmon great for salmon patties.
