San Quentin Things to Do
I'm surprise no one ever posted a tip on San Quentin (SanQuan as the bro's call it). Its a maximum security prison north of San Francisco on a small peninsula and opened in 1852. You can't miss it when you cross the bridge on 580. If you're "fortunate" enough to have friends "living" there, you can visit..see the web link below.
This is the prison where Johnny Cash made his famous show in 1969.
