Re: Any DC area posters...
One of the newer attractions you might enjoy is the Smithsonian Air and Space Museum's new facility at Dulles. It has a space shuttle, an Sr-71, the Enola Gay, and a couple dozen other planes, plus an observation deck overlooking Dulles.
Alexandria, VA is great for shops and restaurants, and it's on the Metro route. Georgetown is another great area for nightlife.
Makes all the routine posts.
