Thanks for the input Wndotinter. I will check into Speedy. I wonder if the replacement glass has the same "black dot" shading on the top above the rear view mirror. I find that effectively hides my radar detector.
Nemesis8: Actually my wife was driving when it happened. She was on highway 167 (Valley Freeway) in Auburn. A rock hit the glass and left a ding with the start of crack (about 1/2 inch on either side of the ding). The next day, the crack grew to its present size. I wonder if the combination of cold outside air and the hot defrost air caused a thermal stress in the glass which caused the crack to grow so quickly?
I guess that's what I get for letting my wife drive my baby.
