Fixed gears have boomed in popularity over the past few years, according to Euan Fisk of City Bikes in Adams Morgan. The coolness factor comes from two sources. First, experienced cyclists seek out fixies because riding takes a more-advanced set of cycling skills, so it's a new challenge to master. Second, much of the cachet of a fixed gear comes from building it yourself like a cash-strapped messenger, slapping on some anti-car stickers and ending up with a bike unique to you.
the law regarding fixies and handbrakes in D.C. was changed, as was reported by bikeportland (I know I got scooped by an out of town blog, thanks to Graham for the link). Thanks to WABA, fixed gear bikes no longer require separate handbrakes. It's a small thing, but it's a good change.
