(700 Constitution Ave. NW; free) Constitution Day Family Activities at Boeing Learning Center Federal Triangle | Wednesday, September 17 Parents and kids can channel the penmanship of the Founding Fathers by reenacting the signing of the Constitution a mere 227 years later. The National Archives and Records Administration will provide quill pens for children to apply their own John Hancocks (or, in this case, George Washingtons) on replicas of the great document. Crafts and costumes will also be on hand to add to the colonial festivities.
