In his new book Door to Door: The Magnificent, Maddening, Mysterious World of Transportation, Pulitzer-winning journalist Edward Humes raises serious questions about the human cost of our automobile-reliant society given how cars are responsible for killing thousands each month (with an estimated 38, 300 deaths blamed on vehicles in 2015). It's a sobering point that draws attention to not only the fragility of life, but the need for reform -- an idea that is the heart of the Ride of Silence, a silent bike ride that is held annually to remember cyclists killed and injured in vehicle-related accidents. Now in its 13th year, the 8-mile ride organized locally by the Bicycle Coalition of Greater Philadelphia will be held on May 20th, beginning and ending at the Art Museum. The ride is both a chance for quiet reflection on those we've lost and how far transportation in general and individual drivers still need to go to keep us all safe.

Ride of Silence. Wednesday, May 20th. 6:45pm in front of the Art Museum. For additional information, e-mail bike@bicyclecoalition.org or click here.
