LA Times wrote an article that features McKamey Manor. In the article it specifically calls out Blackout followed by Mckamey Manor. Some argue that Blackout was the genre establishing first extreme haunt.
“The 18-and-over Blackout Haunted House in Los Angeles requires visitors to walk and crawl through the pitch-dark maze alone with a protective mask and a flashlight. Speaking is prohibited (although screaming is permitted).
In San Diego, the McKamey Manor home haunt funnels those willing to sign a legal waiver through a gauntlet of monsters that touch, grab and shove their victims.”
