Has anyone ever been brave (or thoughtless) enough to visit this "haunted house" attraction in San Diego, California?

From wiki:

McKamey Manor is a nonprofit haunted house or "extreme haunt," which was founded by San Diego, California resident Russ McKamey and originally located on his property. It is regarded by some as the "scariest haunted house in America" and is known for its violence and cruelty towards its guests, who must sign a liability waiver to get in. The Manor may give its patrons unwanted haircuts, drench them in fake blood, submerge them in water, force them to eat and drink unknown substances, have them bound and gagged or engage in other forms of emotional or psychological torture.

The house permits just a handful of patrons to enter each weekend and guests are not required to pay an entrance fee. Instead, McKamey accepts payment only in dog food for his pet dogs. The tour can last anywhere from four to eight hours and no guest has made it all the way through, despite there being no "safe word" that allows guests to leave prematurely.
The house operates year round, and there is a waiting list of over 24,000 people. As of November 22, 2014, a woman named Sarah P. held the record time at McKamey Manor, enduring six hours.

I actually first heard about it through one of the Facebook groups I'm currently in, and everyone has their own opinion on it. Personally I could never do it - and I honestly don't understand how anyone could actually *want* to sign on for something like that. I guess it definitely provides an entirely different kind of scare but .. no, not my thing. :/ I'll just stick to the haunted hayrides.
