Terror Behind the Walls at Eastern State Penitentiary http://www.easternstate.org/halloween/preview/video.php from article: Intake sets the mood for Terror Behind the Walls, as unearthly and mutated prison guards usher visitors straight into the complex. The route winds through chain link fences, under guard towers, and past the abandoned vehicles left on the property. This attraction will have a new expansion for 2008 with a fresh layout, custom-built animatronic props, high-tech effects, digital sound, and large props from Transformers 2, the sequel to last year’s Hollywood blockbuster, which was recently filmed at Eastern State Penitentiary.
Interesting. I'm kinda curious what props they'll be using. I went to the Mansfield Penitentiary several years ago, and to be honest, I was actually scared. Then again I was either 9 or 10 at the time, and the place has been on TV as one of the more haunted places in the US. Wouldn't mind walking threw that place again, though during the day and withought all the added props and what not.
I'll be checking it out this weekend, so maybe I'll be able to shed some light on this topic, unless somebody beats me to it.
