I would love to hear those stories. I think a lot of other players would as well. We all can learn the most from the 'edge cases' of our community, the constraints you had and the resources available. Necessity is the mother of invention, after all. I think prison DMing would be such an extreme and you may have had to invent things others never would have thought to do. I would love to know what it was like, your challenges as DM that are not 'normal', your players and their psyches, the story you ran, etc.
