Freeway Shooter Really?

I'm always glad to get to the end of the week and have a day of rest coming.  Even though Sundays aren't really restful it's still nice to have the guys home from work.  On Wednesday Mindi and I had it all planned out.  We would drop Trulie off at preschool, take Dave to pick up his car at the dealer, get to the grocery store to pick up stuff to make food for the football team and be home in time to pick Trulie up. As we got to the store and started shopping, Dave called to say he was stranded on the freeway with his car overheating.  We grabbed a few containers of water and some things we had in our cart and left in a hurry. He was about twenty minutes away in the HOV lane where two freeways meet.  As we got closer, there were signs telling us that there was shootings on the freeway and we needed to report any suspicious activity.  It was so scary sitting in the car with traffic passing us at least 70 miles per hour and wondering if someone was going to start shooting at us.  It all worked out okay and we found someone to pick Trulie up for us and we got our groceries and got home safely.  Dave only got a few more miles down the road before his car died but he got some other guys to go help him.  Whew!  While I was telling Rich how scary it is to think there is someone shooting at people on the freeway, he acted like it was no big deal. He just doesn't worry about stuff like that and he's usually right.  So far no one has been killed but I still wonder what kind of a person would just randomly shoot at cars on the freeway? The world is getting crazier by the minute and I don't see it getting better in the near future.
