I think we need them... some folks don't need to be jailed, a facility like this would be much better.
I know the one in Athens, Ohio, was turned over to Ohio University, who has been rehabbing the buildings over the last 30 years or so for additional classroom space, they turned the main building into an art Museum, etc...
but back in the day, it had it's own power plant, dairy, farm, water/sewer system, etc. it was across the (Hocking) River from Town, and the main campus, and up on a high hill...
Here in Lima we Have (Had) 2 prisons that share a Campus, the Newer one is still in use, the older one was closed probably 20 years ago, but was Originally the "State Hospital for the Criminally Insane" it too had it's own self contained systems for Power, Water, they grew their own food... today the remains of their water works is just slowly rotting into the ground. the Dam they put in to make a mini reservoir on Sugar Creek is mostly, if not fully silted up. pump house starting to fall in on itself.
The Land that was my Family's Farm is Right off that property, and the Family Church Across the Road from the water works.... a Few years back, during some renovations at the Church, they found a Random old Water Line, with power Cables right along side that weren't hooked up to anything... Turns out the Church used to get it's power and Water from the State hospital across the Road.
