All You Need Is The Summer Of Love: How 1967 Sparked A Revolution The summer of 1967 has taken on an almost mythical magic, a psychedelic summer of love with beautiful people turning on, The year 1967 was designated the “Summer of Love” when somewhere between 75,000 and 100,000 youth flooded 25 blocks in San Francisco’s Haight-Ashbury district. Beforehand, the neighborhood was home to a small community of “hip” residents interested in art, music, theatre, and literature. FN9q9fT.
