spokesperson for Bohemian Grove say the people that gather there “share a passion for the outdoors, music, and theater.”

The club is so hush-hush that little can be definitively said about it, but much of what we know today is from those who have infiltrated the camp, including Texas-based filmmaker Alex Jones. In 2000, Jones and his cameraman entered the camp with a hidden camera and were able to film a Bohemian Grove ceremony, Cremation of the Care.

During the ceremony, members wear costumes and cremate a coffin effigy called “Care” before a 40-foot-owl, in deference to the surrounding Redwood trees.

Bohemian Grove’s spokesperson calls the ceremony “a traditional musical drama celebrating nature and summertime.” The spokesperson also said that while Jones’ comments are inaccurate, the footage is real.

Watch the controversial footage of the ceremony below:

Another infiltrator, Spy magazine writer Philip Weiss, posed as a guest for seven days in 1989, when the waiting list was 33 years long and the grove had several thousand members. Weiss published the article “Inside Bohemian Grove,” writing: “You know you are inside the Bohemian Grove when you come down a trail in the woods and hear piano music from amid a group of tents and then round a bend to see a man with a beer in one hand ... urinating into the bushes. T

his is the most gloried-in ritual of the encampment, the freedom of powerful men to pee wherever they like, a right the club has invoked when trying to fight government anti-sex discrimination efforts and one curtailed only when it comes to a few popular redwoods just outside the Dining Circle.”

Former President Bill Clinton once told a heckler, “The Bohemian club! Did you say Bohemian club? That’s where all those rich Republicans go up and stand naked against redwood trees right? I’ve never been to the Bohemian club but you oughta go. It’d be good for you. You’d get some fresh air.”

The Sonoma County Free Press, which has published investigative stories on the grove since at least the 1980s, says activities include plays and comedy shows in which women are portrayed by male actors, and Lakeside Talks, in which high-ranking officials speak about information not available to the public. The group calls them “public interest talks.”

Protests take place at the Bohemian Grove nearly ever year. This year’s protest is organized by the California State Greens and endorsed by other social activist groups.

Bohemian Grove’s 2011 retreat begins in mid-July. We don’t suggest any infiltrators try to make their way through the entrance, guarded by camp valets and redwoods some 200 feet in height. It didn’t end too well for the last Vanity Fair editor who tried it.
