Thanks for the post. I know someone who was in the same situation as you were on September 11, 2001. My best friend's brother was at the Pentagon (on the opposite side of the building from the impact point). Thank goodness, he was ok.
I have a special memory of the Pentagon. In the summer of 1997, I traveled to DC to visit my brother. We watched the 4th of July fireworks from the parking lot. It was something that I will always remember.
