Just a thought to put out there...where would you say is the best places to meet hippies in your area? I think here in SoCal it's gotta be either Venice (LA) or Laguna (OC) beaches...
I live about 5 minutes away from Hippie Hill in San Francisco's Golden Gate Park. Thats a great place, the entire Haight/Ashbury neighborhood is cool as well. San Francisco in general is a cool place. Berkeley as well.
