Philadelphia's favorite haunted house is now America's favorite haunted house.
"Terror Behind The Walls" at Eastern State Penitentiary has been named the number one haunted house in the US by AOL's "City Guide."
Sean Kelly is program director at the former prison at 22nd and Fairmount:
"We've been the best for a long time. It just took a while for people to notice."
I went through a new section of Terror Behind the Walls. Frankly, I think they need a new word for terrifying. This woman went through the exhibit with me:
"Very, very scary. My heart is racing. My heart is racing. I'm shaking."
