I dreamt last night that I was driving to Washington, DC, but then somewhere near Philadelphia, decided that I forgot something at home, and that the weather was so lovely that I'd go back home and go for a bike ride. And this was all possible within a three or so hour drive, because that's how dreams work.
Imagine my disappointment on waking to below 0F windchill. Yeah, even though it's sunny out, I'm not going out for a bike ride. Nor am I within a three hour drive of Washington, DC, so visiting a Smithsonian, the National Archives, etc, is out for a quick trip.
