Spring Break Idea: Boston or DC

Can't take off for the week for a trip out West?  how about a long weekend in DC or Boston? 

I have posted enough on both that you can just follow my threads for fun things to do in DC or Boston.

On our last visit to MIT someone had mysteriously cleaned out Olin's rain garden. What would it look like now?

In DC you could go someplace familiar, like Dumbarton Oaks, to see it in a less familiar season. 





Or you could visit the new Capitol Visitor's Center.

There is so much to see there that you'll find something new even on your 10th or 20th visit as long as you are looking around.
