Frost, I scraped it off my car windows yesterday. This is the first time my car has been through freezing temperatures since the hooligans broke out the back window. Mysteriously after they broke out my side window, a crack appeared on the right side of my windshield. For a while I watched it eek its way up the window, until it got about 8 inches long. It'd been that way for eight months, but now it is growing again. I blame the freezing temperatures. In one direction it now touches the edge of the window, but the other end still has at least another foot or two to get to before it can dead end. Should I be worried about it? Right now it is just kind of fascinating. I wouldn't put the money in to fix the windshield anyways.
