Metro Smart Spy

You have officially signed on to Operation Metro Smart Spy. DC has always been a hotbed of espionage activity. In almost every street corner or back alley, spies have left their mark on the District. Your mission, should you choose to accept it, is to find these various historical moments hidden on spy ads throughout the Washington Metro system. Scroll down for more intel.

Every week @intlspymuseum and @wmata will tweet a clue about a cloak and dagger site on the rail system. Once you find the secret site, tweet a stealthy selfie with the photo clue and #metrosmartspy. This will officially enter you in the contest, with a chance to win the ultimate spy prize! Each week a new winner will be selected.

Best of luck, agent.
