Documentary filmmaker Ron Mann joined Hollywood actor/hemp activist Woody Harrelson as the thespian traveled up the West Coast preaching the merits of natural, organic living, the result of which is Mann's 2003 film, Go Further. In 2001, Harrelson and a group of friends and other like-minded individuals hopped on bicycles -- accompanied by a psychedelically decorated bus converted to run on hemp-seed oil -- and thus created the SOL (Simple Organic Living) Tour. Along the way, the actor made many stops which ranged from speaking at college campuses to meeting up with 1960s counter-culture guru Ken Kesey (who died not long after). The SOL group encountered a number of people that also lead pro-ecological ways of life, as well as some other folks that were just as skeptical or hostile toward the neo-hippies. Go Further premiered at the 2003 South by Southwest Film Festival.
