Satan's Hollow in Cincinnati, Ohio - Haunted Portal to Hell (http://www.youtube.com/watch?v=ajGYxTfEv-s#ws)
Funny, I went deep into these tunnels with two friends of mine (and a third who got weirded out by the closed-in feeling and refused to go more than thirty feet) one summer when I was home from college, and at the time I didn't know they were supposedly the most demonic (yawn) place in the region, I just thought they looked like a much-spray painted teenage stoner hangout with many years of use: hey, now I know, eh? :lookingup:
