I had to go back and see if Indiana was listed. I bet it has something to do with the produce staying local.
We have tons of farmers markets, every little town has at least one. Big towns have multiples. And everybody has their own garden plot it seems like. But I do think everything here just stays in the local area. Nothing wrong with that. We just don’t have any big commercial enterprises. Maybe that helps keep the price of land low.
When I worked every growing season employees brought in their produce and either sold it very cheap or gave it away. It was always gone by the end of the day. And most people canned food from their gardens. Cannery goods was a very good gift for Christmas. And we have our wineries.
