I just got my car out of the body shop one winter when I was in my 20's. I was driving under a limestone cliff with a huge set of steps running up it. All of a sudden snowballs started raining down, pelting my car. I was pissed, but kept driving until I got around the curve. Then I hammered it, drove all the way to the top and parked a block away. I found a piece of heater hose and folded it in two and snuck across the walkway. I saw five kids hunkered down watching for more cars. They saw me and ran. I chased them and caught 3 of them before the others gave up. I gave them an *** chewing and let them go having learned their lesson. It could have been rocks and someone could have been hurt. I'm sad about your damage, but all in all, I'm more happy you weren't hurt. I still wish you would have caught the little bastard!
