In 1966 the movie “The Russians Are Coming, The Russians Are Coming,” was filmed along the local Mendocino-Sonoma coast. In the plot, a lone enemy submarine crashes offshore, igniting a runaway rumor chain that almost leads to a machine gun battle, hostage taking and a U.S. Air Force strike. We can only imagine that if the players in the film all had Facebook and Twitter accounts how much faster the rumors of attack would have flown and how World War III might not have been avoidable.
