In 1971, a caravan of 60 brightly painted school buses and assorted other vehicles carrying more than 300 hippie idealists landed on an abandoned farm in central Tennessee. They had a mission: to be a part of something bigger than themselves, to follow a peaceful and spiritual path, and to make a difference in the world. Out to Change the World tells the story of how those hippies established The Farm, one of the largest and longest-lasting intentional communities in the United States.
