The scenario turned out to be a "dirty bomb" - actually more than one. I was involved WAY WAY on the outside - we were supporting a group that was supporting a group that helps (We were supporting SATERN, which supports the Salvation Army, which was providing canteen services to "victims" and to the Fire Dept. We are no where near 1st (or even 2nd) responders, but it's fun to get invited and see what's going on - BTW I've never seen that many fire trucks in one place at one time before that
