I toured the military prison in 1991 while attending CAS3 at the war college. It was a required tour. However, one young (and very dull) officer in another class thought those rock walls would be neat to do some rock climbing on. Needless to say the MPs and sr. officers had a slightly different view of this quickly former officer, particularly when it came to the potential of facing the inside of the walls instead.
Yikes, now this was not a story I thought I would read! Former is best for that officer.
