Many of the haunts featured in "The Houses October Built" are real locations and to help promote the film (which comes to theaters, VOD, and itunes this Friday - 10/10/14) they've released this map. Several major/noteworthy haunts are marked on this map with little jack-O-lanterns, but the blue skulls mark locations that appear in the film. Too bad most of the locations are southern or on the East coast, I would have loved to take a trip to one near by.
If you aren't familiar with this new found footage film yet I've added the trailer below. I personally think this trailer shows a bit to much so view at your own risk!
