(FILM) This long-awaited documentary by Portland filmmaker Bill Daniel is a beautiful black-and-white foray into modern hobo culture. Scribbled onto the side of boxcars all across the country is a minimalist line drawing of an unhappy cowboy in a wide-brimmed hat and the words "Bozo Texino." Who's responsible for the graffiti? Daniel rode the rails for 16 years to find out. (Central Cinema, 1411 21st Ave, 686-6684. 6:30 pm, 8:15 pm, 10 pm [late screening 21+], $5.) ANNIE WAGNER
