I was one of those who tuned out after the first hour! BRUTAL! Anyways, I have always heard of Alcatraz being haunted. In fact, when I went to SF about 10 yrs ago, I went on a ghost tour and got the specifics of the hauntings (that they even mentioned last night) the day before I was scheduled to go on a tour of "the joint". When I got to the place, I tried to see if there was anything to experience, and got zippo, even in the dreaded cell 14! Rumor has it, that when they were filming the movie "The Rock", the film crew experienced a lot of paranormal activity. Even caught someone playing the tune Taps on audio. I can't site sources of said rumors because it was way back when the film came out.
Otherwise, the show was a waste. Even Josh looked awful by the way! It was pointless because we all knew that no one would be allowed to ask a quesiton that might rock the boat a little. When the audience started asking quesitons, I was waiting for someone to ask, if you were a tree, what would you be?
Did anyone catch the mention of the Stanley Hotel? I love how they still claim it to be so haunted yet by their own admition, there was perfectly explainable reasons for what happened, i.e. the glass breaking.
