We went Saturday night and I can honestly say, this is the BEST haunted attraction I have EVER exerienced!!!  I don't want to give away too much, but this place engages ALL OF YOUR SENSES!!  They mess with your sight, your sense of smell, even your sense of balance!!  The details and work they put into this event are amazing!!  These are professional actors, stuntmen, directors, stage techincians, and it shows!!!!  And a warning: this is not a haunted attraction for children.  There are some very creepy and disturbing things in there... which is a good thing.  If fact, it's a GREAT thing.  Get more info here.
