Diggers were a group of activists in the Haight-Ashbury district of San Francisco during at least 1967. They were most famous for operating a sort of "open air soup kitchen" in the Golden Gate Park Panhandle. They also provided free food at the Human Be-In.
According to Jessica Willamy, they were were "named after some ancient English commune or something". Comprised of "poets, painters and street actors", they were trying to establish a "socialist utopia". Thus, they wanted hip businesses in the Haight to share their wealth with the community. They also were largely opposed to the Summer of Love; Jack Stimson said they thought it was getting overhyped and that it was "going to bring a lot of undesirables to the Haight". (PROSE: Wonderland)
