I'm clear across the country and was between jobs at the time, my wife and I took shifts for day's and weeks watching the TV in disbelief.
To this day I still can not bring myself to watch anything more pertaining to that day. I recorded "rebuilding the WTC" thursday night but can't bring myself to watch it. It is one of a very few day's in my life that I can remember exactly where I was and what I was doing, I will never forget it.
