Growing up in East Texas, my body will not be shocked at all with pinto beans in a SHTF situation - I grew up on them. We had many farms in our family, and I think the only veggie I ate out of a store-bought can was early peas. All other veggies came from Mason jars.
As near as I can figure, I am a 10th generation Floridian. I know one branch goes back well into the 1700s and all in this same county.
I was born on a subsistence farm but we moved to Panama City when I was four. I guess we were a bit like the Clampets without the money. We grew a vegetable garden in the city limits and also raised and butchered a hog.
It has been too long and I am too old to go back to farming but I would plant a garden.
I am fortunate in one way. I have a large variety of fruit and nut trees on my property. During the Summer I have a huge grape orchard plus plums, apples, and Japanese persimmons which are really good. The persimmons and 12 pecan trees produce in the fall. The only thing I have during the Winter are satsumas.
I couldn’t live on the fruit alone but they sure would help.
Actually the pecans, grapes and pears produce more than I could eat while they are in season.
