21. Bohemian Grove
About 75 miles north of San Francisco you will find a 2,700-acre redwood region called the Exchange and every year during the last few weeks of July, some of the richest, most powerful men meet to drink secret conversations. There have already been a few infiltrators that have managed to sneak in, although you must be a member of the Bohemian Club to gain entrance into the camp. Among them were Texas-based filmmaker Alex Jones, who entered with a group and a hidden camera, and Vanity Fair editor Alex Shoumatoff, who was arrested for trespassing in 2008.
