Modern audiences demand extremes; torture porn franchises such as Saw and Hostel have now migrated to the mainstream. Less well known is this boom in “extreme haunts” in which people sign liability waivers and pay more than $40 to stumble through dark, dungeon-like places where actors grab and manhandle them to amplify the frights. The pioneer, Blackout, has staged slick events in New York, Chicago, Los Angeles and San Francisco. If things get too disturbing, punters yell a contractually stipulated “safe word” to exit the fantasy.
McKamey Manor, in contrast, does not make money. It operates as a nonprofit, taking just a handful of visitors each weekend and accepting payment only in dog food. It is also unique in not having a safe word, says Jon Schnitzer, who is making a documentary about extreme haunts.
“This manor gave me actual nightmares. It’s the only one where you don’t decide when to quit,” he says. That can be an issue when you’re being being bound, masked and held under water, slapped and stomped on, and compelled to eat your own vomit.
