When we lived in the county, we lived on a sharp curved highway. In the fall when they harvested sugar beets and onions they stored the excess up on the hill above our house. When they were in full process working with both beets and onions, they would haul them to the factories for months.
I never had to buy any food for my livestock or onions for my family or friends. I had a steady supply rolling off the trucks into my borrow pit from the overloaded vehicles. I sent my kids to pick them up. Pigs couldn't eat the beets fast enough
