Celebrate Washington's Birthday at the famous Revolutionary War park. On Presidents Day visitors can meet portrayers of Martha Washington and General George Washington at the visitors center, while listening to period music performed by the Colonial Revelers. Children will be able to make their own tri-corner hats and design birthday cards. Mrs Washington will present a birthday cake. Children can also enlist in the Continental Army and follow Washington as he leads troop drills. All these events are free and open to the public.
