The Psychadelic Shop
The Psychadelic Shop, also known locally as The Head Shop, was located directly underneath the offices of the San Francisco Oracle, at the exact corner of Haight and Ashbury Streets in San Francisco. It was opened in 1966 by Ron and Jay Thelin. According to Jessica Willamy, it was "the symbolic head" of the Haight, providing information and materiel necessary to take whatever recreational drug one desired. It was a particular proponent of LSD.
The Second Doctor, Ben and Polly visited the shop in January 1967, at which time the Doctor was particularly interested in various bongs and pipes that were on offer. ([[PROSE}]: Wonderland)
