Driving up the street last night at 6:30 PM I saw what appeared to be a fox roaming along the side of the street near some backyards right as I was about to turn onto our street. I've known for years there are foxes in the woods near our neighborhood, but this is the first time I've seen one roaming around near people's houses instead of just moving around near the woods.
Didn't look big enough to be a coyote, although I know those have been seen in western Fairfax County and in Rock Creek Park.
