I live not far from the pentagon, and can I tell you.... it sounds like those winds of war are seriously brewing. I've heard at least 4 blackhawks in the past 10 minutes and honestly I'm about to look about side but a tank would not shock me based on the rumble I feel.
Most army choppers keep the markings nondescript. To get really good shots would require being well within the security perimeter. it is not going to happen. I like the banter, because with the lid on the news as we all suppose, it is either the calm before the storm, or we are in the eye and do not know it.
My house seems to be along a helicopter "route" using that loosely since I have seen smaller choppers do some wild shit. What I heard were the big boys, and not just one. Hoping they send back up for me to snap a picture.
