In the DC metro area, it’s Car Free Day, encouraging commuters to consider alternatives to driving. If more people biked, took transit or walked, not only would it free up some room on the highways and roads, it would reduce air pollution and encourage exercise. In fact, the DC metro area has some of the lowest air quality in the country. Although as a region DC has some avid runners and great trails, more people could take advantage of the area’s outdoor offerings especially on weekends. The events are in conjunction with World Car Free Day, each Sept. 22. Learn more about the events around Car Free Day here.
