I need some advice.

I used to work prison games back in the '80's when I was in Kenai, Alaska. Best games to work. Players made the best out of the only opportunity they had for rewarding recreation. Sportsmanship was great, partly cuz they knew they had a guy observing from the corner of the gym who could make things bad for them if they got out of hand.
The prison teams were part of our city league back then. Of course, they had no away games that I can remember.
Some city league teams' players had to conveniently miss their game at the prison, likely due to outstanding warrants, I think.
