Basically, bikes rule. Sure, running needs only shoes, and the tech weenie thing can get way out of hand, but at it its simplest, there’s something about a bike and a spring day that goes right to the heart of the good life. There are lots of crappy things that can make your bike reality a little hellish, but they’re worth the risk. Honoring the good, the bad and the brutal of it all, Filmed by Bike (April 13-15) is a film festival dedicated to the spirit of bicycle culture. Comprised of 90 minutes of films, none longer than eight minutes”brevity being the soul of wit and all”this event deserves a place on your April calendar. Opening night promises plenty of, ahem, interactivity, but the following evenings should be tamer. Keep the rubber side down.
