For many people, Bike to Work Day (which is today) is a reason to put air in their bike's tires and see if their chain is too rusty to get them to work on time. And as a growing list of photographs shows, many people who follow NPR online also ride to work.
Bike to Work Day is this Friday, May 18. And that prompts a question: Do you bike to work? If so, you should prove it — by taking a photo of yourself with your bike. Then share the picture, and we'll consider it for NPR's Bike to Work Day gallery.
