DC is amazing. Vast amounts of things to see and do. Be aware that the city is built on a series of small hills -- when walking to and fro, one gets a much better workout than one initially anticipates.
Nonetheless, I had a great time. I saw lots of things, learned a few things, and enjoyed the 30+ weather. (Don't think I burnt though.)
Now it's working over the long weekend and enjoying company and settling back in at home. I'll be sure to get pictures up shortly and perhaps a few stories from my trip as well. Happy Thanksgiving!
