Crazy! Glad to hear that you weren't part of the action.
I think about this kind of thing fairly often whenever my routine is interrupted or when I'm running late. A couple weeks ago, we were up near Winter Park and running about 15 minutes behind our planned schedule.
Berthoud Pass ended up being shut down all day due to a fatal accident. Had we been on time, we would have been on that stretch of road almost exactly when the accident occurred. Unfortunately an hour and a half ride home ended up being an 8 hour road trip to get home. Still glad to not be a part of that one.
