Weathermen

The Weathermen, also known as the Weather Underground, was a terrorist splinter group in the United States. It was formed by a small group of former members of the defunct [Students for a Democratic Society]?, which had dissolved in 1969.

The name of the group comes from the Bob Dylan song "Subterranean Homesick Blues", which featured the lyrics, "You don't need a weather man to know which way the wind blows".
