Old video, but its from the Rocky Mountain Testicle Festival held at Rock Creek MT (Sorry I couldn't find a more current one, but I'm at work). According to Maxim, it's like the 4th or 5th largest private party in the nation and its a fucking blast. It's really hard to explain exactly what goes on at Testy Fest, but suffice to say its lot of nudity, sex, drugs, rock and roll. The best time is the shuttle from Missoula out to Rock Creek. A yellow school bus full of drunk people is pretty wicked.
As far as the Testes go, I've had them twice. The first time I think they tasted like undercooked chicken fried steak. They were pretty gross. The second time I had them they were way crispier and a lot better (however, the amount of substances in my system at that time was not really conducive with eating).
