Went to Eastern State after seeing it on "Ghost Adventures". It was a free preview day, which was an extra bonus. Tour begins with a history of the penitentiary system, and how ESP differs from other prisons. The place is really dilapidated, which is part of the appeal. We went on a cold rainy day in March--be forewarned that the place is not heated and dress accordingly. It was interesting to see it, but the audio tour areas are rather limited. If you can, I would go on one of the free scheduled tours included in admission because you can see more. The architecture is the most interesting part of the place-- I did not find it creepy or haunted at all, but fascinating in a more historical way. Quite a contrast to the prisons of today.
