The posters began to appear around the city just after New Year’s, 1967. “A Gathering of the Tribes for a Human Be-in…Bring food to share, bring flowers, beads, costumes, feathers, cymbal flags.” On Saturday, January 14, a crowd of young people began to form on the open fields of Golden Gate Park. Throughout the day, local bands — not yet famous — took turns on the stage: The Grateful Dead, Jefferson Airplane, Janis Joplin’s Big Brother and the Holding Company. Poets Allen Ginsberg and Gary Snyder led Hindu chants to the bouncing rhythm of finger cymbals. Timothy Leary addressed the crowd, urging them for the first time ever to “turn on, tune in, and drop out.” Owsley Stanley, the rogue chemist credited with manufacturing the period’s highest-quality LSD, donated 75 turkeys for sandwiches — the bread was sprinkled lightly with crushed White Lightning acid. At one point, a skydiver descended gently into the crowd, borne by a white parachute.
