Saarinen in Washington DC

Thanks to marnaw for telling me about an upcoming exhibit at the National Building Museum in Washington DC that will feature Eero Saarinen's work. It looks like the exhibit will coincide with when the Architecture Club is in DC at the end of the semester, in early May, so that will be on the list of things to go see.

I know Fallingwater is on the list, but any other destinations in the DC area are welcome and appreciated.
