If anybody sees a group of people running around hurdling obstacles outside the Silver Spring Metro station, they're either running from the cops or participating in a parkour jam. What the hell is parkour, you ask?
Parkour is a physical discipline of French origin in which the participant — called a traceur — attempts to pass obstacles in the fastest and most direct manner possible, using skills such as jumping, vaulting and climbing, or the more specific parkour moves. The obstacles can be anything in the environment, so parkour is often practiced in urban areas because of many suitable public structures, such as buildings, rails, and walls.
According to this site, Silver Spring may be the best place to parkour outside France and the U.K. -"There are so many spots in Silver Spring that mirror parts of London". Really!?
