I just looked this up. A trailer is a preview or movie advertisement. Last summer, Trevor Velin, a New York filmmaker who has become a good friend, came to Colorado to make a documentary film on pack-burro racing. Trevor was out last week and wired me for some additional voice-over. He showed me his rough cut of the film, and some of the scenes moved me to tears. He really found and explored some raw nerves in the three characters — myself, Curtis Imrie and Roger Pedretti. Sport meets art head-on in this documentary. The movie is due out this summer. For now, here is his trailer for the film.
