The D.C. area's annual Bike to Work Day returns Friday, May 15.
It's not just a day of typical bike commuting, either -- caravans get like-minded cyclists together, and pit stops will give out water and snacks to bike commuters. You'll also have the chance to score a free T-shirt and enter raffles for bicycles.
There's nearly 80 around the D.C. area -- find the closest one to you here.
