I first saw this film in the cinema tent at Bonnaroo last year, and I was very inspired.. the film advocates organic vegetarianism/veganism, biofuels, bicycling, hemp, and saving the environment. They ride down the west coast in a big biofueled bus teaching people about all these things.. The best part is all the top-notch musicians in the film, from String Cheese to Dave Matthews to Anthony Kiedis to Bob Weir! I thought I'd post about this movie here at HipForums because it's definitely a hip kind of movie.
I tried to rent it for about 6 months, but it was always out. My wife bought me the dvd for my birthday. It's an awsome movie with lot's of good info.
