Don't bet on it, you priced feed lately? Over four bucks a bushel for anything that'll make a turd! That bushel will make about four gallons of alky, burn that instead.'Course, ya can't eat your truck when it quits. Or fertilize the veggies with its exhaust.
If we all went back to horses, there isn't enough land to grow the feed they'd need, let alone bread for us to eat. The good ol' days are gone for good.
