It's amazing how 9 years goes by - yet, to me, it's as clear as ever. I was working about 10 miles from the Pentagon on that day. A very sad moment.
It's also ironic how it has changed some of my ways - in a musical sense. At the time, I was really into Blues Traveler. Had 3 or 4 of their CDs in my car all the time. Loved what they did. However, 9/11 put me in such a "funk", I can no longer listen to their music because it takes me back to that time - from a memory sense. It basically took me about 2 months before I even started to get back into music following 9/11. Even then, it was a very slow pace.
Edit: I just realized this is post "666" for me in the 9/11 thread. Yikes!
