Yes, they do! Until a few years ago, this prison was self sufficient. They cut back a few years ago, but it's amazing what all they do. They have a dairy that provides milk to Turner dairies. They grow tons of vegetables, and send overstock to other prisons in the West Tn area. They have a small engine shop where I got 2 craftsman mowers overhauled and painted for parts plus $20. They have a leather shop where we get custom belts, cell holders, whatever you can think up. There is an upholstery shop, they cut and sell firewood, and have orchards.
It would be a great place if it wasn't for the 2600 maximum security inmates...lol. There are even a few good fishing holes, when you can get permission to fish.
We still have those in Texas too. They gotta farm it and then process it and that's their meals. Seems fitting to me.
