Golden Gate Park
From Tardis Wiki, the free Doctor Who reference
Golden Gate Park was a public park in San Francisco which formed one of the boundaries of the Haight-Ashbury district of the city. In the mid-late 1960s it was the venue for a number of free concerts by the likes of Jefferson Airplane, Janis Joplin and the like. The largest and most culturally significant of these was 1967's Human Be-In.
It was viewable from several locations in the district, like Oak Street. The Diggers would often open an "open-air soup kitchen" there, and provide free food to a number of people. (PROSE: Wonderland)
