Island guy Elliott Vecchia’s new movie Natural Selection is a skateboarding film shot around Boston and Lowell. In a trailer for the movie, a cast of skateboarders do what they do best. They fly on their boards over stairs, railings, grassy hills, buildings, clouds; it is as if nothing is beyond the reach of their wheels. They do this not in a sound studio or generated on a computer screen. There is no high tech, no instruction manual or team, no coach and most of all no boundaries. It is the ethos of skating. Use what the urbanized world gives you and make it your plaything.
