DC- In your post, you referenced observing very little, if any, aircraft. I've been noticing the same thing- has there been a decrease in regular flights over the past few days? It certainly seems so.
Yes there has been a major change in air traffic here but that is to be expected as we are 10 miles from several "concerns" as the bird flies. I still see some very high altitude traffic, mostly military I think and the "guard" jets that circle the region.
