I was there!
Living, and working in Simi Valley, I remember this day. Namely, because when we (myself and a female colleague) were going out for Indian food for lunch (there's a great little buffet in town) we found the street in front of that dental office blocked off, and had to detour (after getting out and asking people what was going on).
Now, far be it from me to compare the tragedy that occurred that day, and the loss of human life, to the delay that it caused me on arriving to my curry (because it cannot compare, truly), yet I still find it amusing that something from my little town would show up on this site that I've read so regularly for so many years.
