Haight & Ashbury

This legendary intersection was the epicenter of the psychedelic '60s, and "Hashbury" remains a counterculture magnet. On average Saturdays here, you can sign Green Party petitions, commission a poem and hear Hare Krishna on keyboards and Bob Dylan on banjo. The clock overhead always reads 4:20 – better known in herbal circles as International Bong-Hit Time. A local clockmaker once fixed the clock; within a week it was stuck again at 4:20.
