During a trip to Washington DC, we stay at a hotel in Tyson's Corner, McClean Fairfax County, Va. A layover here would usually involve a walk around the local area which contains office blocks separated by wooded plots. The birding here can often be rewarding, but I was picked up by the police last time I tried.
