DC is a cool city/district. My mom lives in Georgetown next to the French Embassy and well, Georgetown University.
Get there about twice a year, seen all the monuments so many times which gives me a chance to see a lot of the smaller off the beaten path stuff. Restaurants there are as amazing as they are diverse (and ridiculously expensive).
Glad you were able to enjoy the DC attractions...it really is a great place to visit, especially for the kids. Thanks for the pics...never gets old.
