I haven’t gone all out crazy preper but I have about 4 weeks with out rationing of canned goods, mre’s, and bottled water. Couple life straws I could use in the crick if it came down to it. Have about 6lbs of honey from the local bee keeper. Keep enough dog food to last the same amount as my own. Considered getting a couple chickens. Picked up one of those Coleman propane stoves I keep stashed away with a good amount of the little green tanks full. My buddy runs a garden every year and I know he’d do some trading for a rifle/ammo which I’m pretty well stocked on plus components to keep reloading. Keep a good med kit around also. I always buy ahead a month or 2 on things like deodorant, body wash, shampoo, toilet paper(unaffected by the shortage lol), paper towels, aluminum foil, zip lock bags. Just simple luxuries that will never go bad, easy to store and could make a good barter item.
