We flew back from Philadelphia on September 4, 2001.
We're going to Glasgow in 3 weeks, but not via London.
I adore London. I adore the tube. When we were there, we took the underground everywhere we couldn't walk.
My friends have mostly checked in, and I the ones who haven't I think are still in Canada after WesterCon. I'm glad to hear that other friends are hearing from folks.
What I've been hearing from Londoners and expats is that they survived the blitz, they survived the troubles, they'll survive this.
