Doubtless you've seen pictures of flat track racing. Motorcycles drifting around a dirt arena at such severe angles to the ground you'd swear the camera was tilted. Inside foot out and skipping along the surface like a flesh-and-bone training wheel. Front wheel cocked at an impossible angle, maybe even hovering a few inches off the ground. Few motorsports offer more dramatic imagery than a squadron of flat track racers rounding the first corner. But it's a sport that can also be beautiful, even graceful, as we see from Evan Senn's short documentary "Fast and Left," released last summer, which follows the flat track circuit around the Midwest. In it we hear from veterans of the sport, superstars, beginners, families, and pretty much everybody in between, explaining not just the mechanics, the zen, and the thrill of flat track racing but also the tight-knit community that keeps the sport alive and thriving.
