To experience McKamey Manor is, you have to be 21 and older, or 18 to 20 and have parents' approval. Then you have to have a sports physical and doctor's letter saying that you're physically and mentally cleared for the challenge. You also have to pass a background test and be screened by the haunted house's employees. After that, you must have proof of medical insurance and pass a portable drug test the day you go before finally signing a 40-page waiver.
