Many years ago, A man who use to work on our ranch was a moonshiner, I was too young to be drinking but my older brother said it was “Really Good” He lived in a line shack about 8 miles up a dirt road and I know my Dad didn’t pay him much, but on the other hand he let him do his thing up there. I know for a fact that old man had an old Studebaker truck that ran on his stuff. So there’s that. Seems a guy could run a few things like a pump or a generator maybe. I think it’s prudent to at least know how in a SHTF.
