No books. My resources and his was growing up in the rural south. I grew up on a modest but productive farm. Raised our own cows, pigs, chickens. Worked 3 gardens with a mule and canned everything we didn’t eat fresh. Grew our own wheat and corn before the Monsanto era to feed our animals. We were self sufficient. Not rich, but never were without, Husband grew up dirt poor several counties away. Went hungry many nights as a kid and vowed he’d never do it again. I taught him what I knew and he jumped right in. We’re more than ready for what could come and we already know we’ll be taking care of several, but we’ve got it to spare and we knew in advance we had dumbasses in the family who were clueless.
