Thea, I live in Washington, D.C. and my mother-in-law is a docent at the Smithsonian. So, if you want, I'll send you info on what's going on. I do know that there is a terrific new permanent exhibit on Kitty Hawk and the Wright Brothers where they have brought the plane down off the ceiling and refurbished it and you can now walk around it and see its details. Also, there is a great IMAX theater and plantarium and a very good redeisgned large display about new research on the solar system.

You can also to on the internet to www.si.edu and there is the current schedule posted there.

Hope that helps.
