May is National Bike Month and the Washington region is celebrating. The TPB proclaimed Friday, May 18 as Bike to Work Day for the region. This is the 18th year the TPB, through Commuter Connections, has co-organized Bike to Work Day, along with the Washington Area Bicyclist Association (WABA). It’s a day to encourage more people in the region to try out biking as a way to get to work.
