The other events mentioned were a lot farther away and a lot smaller. I did think about the possibility of the WTC being a target when I moved to NYC. But I didn't think to worry just because I was in NYC.

After 9/11 I did.

Growing up I remember worrying that I could die at any instant. I lived next to one of Canada's 2 naval bases, I'm sure it was on the list. (When I say next, I mean walking distance.)

Cheers,
Ben
