We will start off by saying this. This is the scariest and most intense haunted house we have ever seen. Ever.
A haunted house that promises an extreme experience that can last up to 10-hours requires participants be medically cleared by a doctor and sign a 40-page waiver.
The McKamey Manor experiences in Summertown, Tennessee, and Huntsville, Alabama, also require visitors be at least 18, insured, and pass a background check and drug test.
Owner Russ McKamey offers $20,000 to anyone that can complete the haunted house — no one has ever made it completely through.
He records each tour on video — for his own protection he says — and then posts them online , showing them quitting in humiliation.
It’s costs nearly nothing to enter: Just a bag of dog food. The website warns of physically demanding environments, but McKamey says the manor is a mental game.
