I dunno, sounds like someone was watching out for you. The wreck almost happened, but didn't, somebody got shot, but not you, and you had a good ride.

I just rode an old beater bike down to Walmart. On the way, a fire truck and ambulance passed me, they both went to Walmart. I figured somebody that didn't ride probably had a heart attack in the bacon aisle while riding the too-fat-to-walk Walmart scooter-cart.
