It appears that a snowy owl is roosting in northern Virginia. In fact, it appears to be roosting at busy Dulles Airport. I am not sure if I will have a chance to go out and see it, but I thought I would pass the word along. More information from the va-bird listserve is here, here, here, and here; with photographs here.
Normally I would not post owl locations, but since this individual has been sitting out in a busy location anyway, I figure that birders would not create too much extra disturbance.
