Besides the Smithsonian Museums and Mt. Vernon, what recommendations do you have for us? We will be going to a service at the National Cathedral (and visiting family interred there) and visit a family friend. Our friend Sarge wants us to stop by the Wall to say hi to some of his friends, and of course we want to see the Korean War Memorial in honor of Grandad Ralph.
Thanks for your tips! (Blogging may be a bit sporadic while we're gone, but please stop in to visit!)
