Out in the Marin Headlands they have a whole exhibit about the missile sites there and around the Bay. You can even interview and listen to presentations by people who were stationed around the Bay during the cold war watching for a Soviet attack. Apparently, the Soviets had a plan to repeatedly nuke the bay to generate huge clouds of radiation that would then spread across the country. http://www.nps.gov/goga/nike-missile-site.htm
