The next station was called simply TRAPEZOID, but I could have guessed as much from the fact that more than half the people getting on and off the train were dressed in military uniforms of one service or another...As the headquarters of the American military and presumed ground zero for any hostile military strike, the Trapezoid had, for me, always been more mythic than real...The terrorists had targeted it on 9/11, and I could see part of the memorial that had been built on the side where the plane had crashed into it.
