A group of us from work went on the overnight "ghost hunt" at the old Ohio State Reformatory in Mansfield..
We didnt really expect to find any ghosts, but went armed with night vision and thermal imaging scopes, audio recorders.. even special hats made from aluminum foil...
just in case...

Its a pretty good time and I recommend it.. They give you a quick tour, feed you some pizza, then turn all the lights off and turn you loose.
