We had one of those minimum security federal prisons in Allenwood Pennsylvania.
It bordered serveral thousand acres of state game lands for hunting in the old Federal Ordnance. My tree stand was right on the prison boundary. The fence was in that bad shape that the cows would get out.
More than once I observed the prisoners in with the hunters, rounding up the cows.
There’s something similar on Eglin AFB, in NW Florida. It’s a place I’d consider committing a crime to get into.
