The obscure test facility sprawls over the treeless ranchland 40 miles east of San Francisco. Last year alone over 300 tests were run at the site.
Starting in April '84 demonstrators began to target Site 300. By the end of the year protestors had infiltrated the site on at least 5 occasions and succeeded in temporarily halting open air testing of the detonators. This disruption of business as usual delayed the underground testing of nuclear warheads at the Nevada Test Site.
In the most recent infiltration, last April, protestors reached the building where Star Wars research I is conducted after they climbed to the roof and hung a banner appealing to Site workers to quit.
The August actions are expected to bring the shutting down of Site 300 one step closer.
