Jerry's post on cyclo-cross yesterday reminded me to look at the bike-related feed on my aggregator this morning, and I wasn't disappointed with what I found: GGW has a really cool entry showing the most popular paths for rental bikes in Washington. Closer to home, the Baltimore bike counts I blogged about a couple weeks back have been posted for a few days, and I've been slothful in not linking them sooner. (The chastising session can now commence.)
Most interesting to me was that the helmet numbers were so high. More here.
