I just watched "The Shawshank Redemption" (it was on free to air tv) and was intrigued by the location they used, so I did a little research and found out it's the Mansfield Reformatory in Ohio. I also found that it's reputedly quite haunted, and there are a LOT of people who have taken photos there which show odd things.

Thought I'd share in case there are others who are as fascinated with ghost pictures as I am (some of the pictures are better than others, obviously, but there are a LOT of orb photos taken in that place, and a lot of plasma pictures, as well...)
