The best one I have been to was, when I went to Universal Studios Hollywood last October..
They had three themed houses Freddy, jason, and Texas Chainsaw Massacre and one big one where they are the crash scene from War of the Worlds into one huge has haunted walk through definately worth the money not to mention everyone in costumes walking around scaring everyone through-out the WHOLE park
Since it was Universal Studios everything looked exactly like in the movies (Obviously)
Didn't there use to be a haunted forrest by one of the drive-in movies?
