"Members of the ultra-exclusive Bohemian Club—2,500 of America’s richest, most conservative men, including Henry Kissinger, George H. W. Bush, and a passel of Bechtels, Basses, and Rockefellers—are known to urinate freely against the ancient redwoods that cover their 2,700-acre property. Have they been chopping down the trees as well? According to one former member turned whistle-blower, the San Francisco–based society may have logged some of its old-growth forest. Drawing on his own Ivy League ties, the author investigates, with a daring sortie into the ceremonial kickoff of the Bohemians’ annual encampment."

More than one reporter has spent time on the members fascination with peeing wherever they please. Weiss snuck in and intervieswe people as well as witnessing the ritual for himself. Here's his whole article.

Part of a letter from a female member of the Sonoma County Board of Supervisors.

"1) Stop trying to convince me that the Grove is totally normal. It’s not. It’s weird. But here’s the thing — I don’t have a problem with weird. So just be honest with me and admit that it’s weird. Try, “hey, I like to hang out with a bunch of powerful dudes in the redwoods and pee on trees and listen to music and hear famous men speak and burn effigies in weird little tent cities.” Because that sounds like West County Burning Man, and I can understand the appeal."

From another article:

"Nowadays, everyone from business moguls to renowned artists sojourn to Bohemian Grove to behave like careless commoners. Journalists who managed to infiltrate the grounds recall men falling over drunk, urinating on the sides of trees, and performing plays in drag."

I think I'm on pretty safe ground to suggest there is a fascination with public peeing going on that's far more than normal camping.
