The Bohemian Grove, a 2,700-acre campground in California, hosts an annual two-week retreat for powerful men including presidents, CEOs, and media moguls. The 'Cremation of Care' ceremony — a ritual involving a 40-foot owl effigy — was secretly filmed in 2000. Former members including Richard Nixon described the gatherings. The club's existence and rituals are now well-documented, though they were long dismissed as conspiracy fantasy.
