[IMGCAP(1)] Lost and Found may have taken a break in August, but the construction around Capitol Hill kept on going. Above, a construction worker uses a jackhammer to chip away concrete around bollards, a familiar feature for federal buildings (hint, hint). Can you identify where this construction is taking place? Check back next week for the answer. [IMGCAP(2)]Back in August, we asked you to identify the building receiving the window washing pictured at left. The structure in question is the Cannon House Office Building.
