I ask this because I was planning on running some errands this afternoon and was greeted by my driver side window shattered. The weird thing is that if someone did break the glass, they didn't take anything of "value" from the car, like a cordless power drill and extra battery, or my MP3/CD player. The door wasn't even unlocked. My neighbor thinks the glass just gave up the ghost, but the temperature changes in the past few days have swung from the mid 30's to the mid 70's. So, I'm confused as to how or why. It was so much fun cleaning out the driveway and the car for little bits of glass all over the place. I did use this incident as an excuse to finally buy a shop-vac.
