I was living and working in Bogota, Colombia at the time. I remember the shock and awe of the thing...totally surreal. But being an American in another country lessened it for me. I was also brought back to reality when a couple of days later, a colombian friend of mine stated to me, "Welcome to the rest of the world". I guess being born and raised in a country with a 40 year civil war, where thousands die every year, it puts everything into perspective for me.
I just hope we can move on from this...eventually.
