Ray- I can never do what the guy did with a hammer, but understand the gut wrenching feeling decreases after the very first impact. After that the rock hitting my windshield didn't feel so bad. But, I may need to get it filled so the temperature changes or stress cause the spyder web effect.
Michael McKelvey- I know where you are coming from. Someone within the family stacked some boxes too close to the speedster. Good thing I had the cover over the car which didn't do any scuff markings.
