There's been a lot said about plows, where they have and haven't gone, and the city has a website where you can track them yourself -- snowmap.dc.gov. It shows a time-series map of where the plows went and what they were doing at the time, which is pretty cool. It only shows today and yesterday, but still, gives you some idea.
Looks like Fairmont Street and large portions of Columbia Heights north of Irving Street didn't have much attention (although maybe they're already clear, but I kind of doubt that for side streets).
If you haven't been plowed or need some more, call 311.
