This collection of films about alternative-transportational lifestyles is "dedicated to highlighting the history and culture of the American train tramp" (i.e., HOBOS), plus their highway-bound and slightly more frightening cousins, hitchhikers. The itinerant festival is currently on a national tour (see, like a hobo! Meta!), screening such intriguing titles as The Great American Hobo, Fruitloop and Arweigian Rick, and Crow Dog, presumably on such intriguing topics as why grain cars are better than coal cars, having a dog who is also a best friend, hobo stew, and freedom. (Central Cinema, 1411 21st Ave, 686-6684. 7 pm, $8.)
