wife and i went to visit a friend, drink margs and watch football last sat. sat, no crack. sun morning when got back to apartment wife woke up from drive and asked what happened to windshield. what?? using my college education and deductive reasoning i said "$h!t". didn't notice it b/c of the rear view mirror. crack comes down about 4 inches from roof then left about 5 inches. no visible damage from rocks, so think might be from light freeze sat night. no intention on replacing until it crashes in on me. no digi cam or scanner so no pic avail.
