I was coming off the freeway on my way to work this morning and was waiting in a line of traffic on the offramp. A few cars ahead was an old red pickup truck. I was listening to the radio and half paying attention when I saw a flash come from under the truck, followed by a small "boom". For a split second I waited for the larger explosion that would blow the truck and everything around it into little pieces. This didn't happen, because it was just an old red truck backfiring, but I can't remember ever thinking that I was about to be a victim of a carbombing before today. My world has changed.
