In the summer of 2001, actor and renegade activist Woody Harrelson took a 1,300-mile bicycle trek from Seattle to Los Angeles. Deeming it the Simple Organic Living tour, Harrelson was accompanied by a hemp-fueled bus filled with Kesey-esque stoners. Director Ron Mann traveled along to chronicle all the good vibes. Because of the film's loopy optimism, it would be easy to dismiss Go Further as just a hippie home movie. But Harrelson is never preachy, and the film strikes a balance between humor and advocacy.
