The mckameymanor in San Diego is a rare and violent take on the haunted house experience. You must be 21 to enter the house.
Inside the house visitors will be tied up thrown into a pit full of snakes and covered in fake blood. This house is so popular over 24000 people are on a waiting list to enter the house. So far no one has made it through the entire house. At a certain point the visitors give up and are removed from the house.
