1. McKamey Manor

Russ McKamey operates McKamey Manor in Summertown and Huntsville, Tennessee and Alabama all year-round. Each contestant’s experience can last 10 hours; tailored specifically to them by playing off their fears. Contestants may find themselves bound, blindfolded and restrained – or made to consume rotten eggs or walk 7 meters above water without the protection of a safety net!

Whoever wishes to participate must go through an intense screening process that includes a physical exam, background check and phone screen test. They then sign a 40-page waiver before watching a two-hour documentary of all those who have ever attempted the experience. Critics contend the haunted house is an abusive torture chamber that should be shut down; McKamey maintains it is safe but can be emotionally and psychologically distressful.

4. Blood Manor

Blood Manor is a 10,000-square-foot maze of terrifying delights. Considered the scariest haunted house in NYC, PAPER warns it may be too intense for some guests. 75% of its attraction has been revamped this year or added; that includes an interactive haunted battlefield which pays homage to celebrity photographer Matthew Brady’s studio at Blood Manor.

Now that the pandemic has struck, some haunted-house industry tactics that were once effective are being reduced or curtailed. Janelle Mercado of Blood Manor oversees her cast of sinister characters and menacing monsters; previously she would enjoy whispering gibberish into guests’ ears or prodding her prosthetic eye with a fork; however now it’s more effective to remain six feet away.

PAPER recently met with Blood Manor co-owner, Jim Lorenzo, to gain more insight into its history and what makes it tick. Here is what he had to say.
