5 to 10 acres in a defensible place with an off the grid water source. Greenhouse. Fractional precious metals in .223, .40, .45, .22LR, etc. Some stock like chickens, a pig or two, beef on the hoof. Hunting skills. Stashed starches in enough quantity to live for at least two years. Heirloom seeds.
Hard times are coming. Harder than most Americans can even imagine. Harder even than The Great Depression. Root, hog, or die, and the weakest go to the wall. Those who survive the culling will create a society with a low tolerance for bullshit and high expectations of the people it accepts as full fledged members.
I hope that’s what the unculled do. Hope is not a plan.
