I'm going Sept, 7, 2011. 1, in conjunction of a trip to Ground Zero.
The Last Time I was there, they did Two. A generic episode, and the Ghost Hunters episode. And yeah they had to stop tape for at least 15 mins to figure out why the question was Blanking out. Then they were like "Forget it, we can edit". I haven't seen the episode per say . Yes there is testing prolly gonna be my last for this year....
