Speak on it bro.
Spent many a trip up in DC/Northern VA. Most definitely they got hidden defenses everywhere.
I was up there when dude went postal at the Navy Shipyards a few years back...barely got a flight home before they cleared the airspace.
Even from a historical standpoint, DC was strategically a place George Washington, who owned most of the land here, decided to move the capital to after the incident that happened in Philly...Hard to invade - a reason why people hate driving in the city because if you don't the city like that the streets are very confusing and you can easily get lost....
I've only been to Obama's inauguration, but let me tell you the amount of security was some shit I have never seen before...
Let's just say every rooftop has military personal with them THANGS that could do some serious damage. On the ground had them Thangs, thangs meaning rocket launchers, on the ground....Like it really was some shit out of the movies...Snippers every where...
If you ever get a chance to see that concert that was done on the lincoln memorial, them boys were walking around the top dressed in all black...All the buildings in the city have them boys walking up top..
It's been rumored to me by true Washingtonians, that there are certain statues throughout the city that look very out of place or just weird, but you don't really pay too much attention to that house missiles pointed directly into the sky...
And just as I type this, 3 presidential helicopters are flying above me right now either taking someone important to or from Andrews Airforce Base in Maryland...
