The Nike Missile base in the Marin Headlands, once configured for nuclear or conventional warheads, has been restored to near-original condition. Configured for nuclear or conventional warheads. After the Cold War, more than 150 city, small towns and county governments declared their jurisdictions “nuclear-free zones,” where research, production, storage and various other activities related to nuclear weapons was discouraged or prohibited. Over the years, most of these ordinances have faded away but some cities like Berkeley and the county of Marin in California still largely abide by them.
