Green Tortoise San Francisco

Have you heard? The Tortiose was a bus that took people across the United States for a very low price. It was mainly used by the Hippies and popular Rainbow. I think it started running out of San Francisco. Does it still exist? Any info or stories from experience would be appreciated

They are always there
