My family and I are traveling to Washington, DC next week and I was wondering if anyone here had some helpful hints or ideas about places to go, stuff to see, restaurants, etc. I know I'm going to see the White House, Lincoln Memorial, Jefferson Memorial, all the War Memorials, Arlington National Cemetary, National Zoo, Washington Monument, Smithsonian, Library of Congress, Supreme Court, Capitol Building, and Union Station. Anything you can think of that would make my vacation better, please let me know.
