The 'Human Be-In' was a happening in San Francisco's Golden Gate Park, the afternoon and evening of January 14, 1967. It was a prelude to San Francisco's Summer of Love, which made the Haight-Ashbury district a household word as the center of an American counterculture and introduced the word 'psychedelic' to suburbia.
