I was driving on I-95 this morning, and suddenly a huge piece of ice came flying off the roof of a truck two lanes over, and hit the right side of my windshield, causing it to shatter. I'm okay, but the car is obviously not drivable, which spoils my plans for the day, at least until we can get to the auto glass place, which will happen after the truck company insurance people get back to us. So if you see a truck spraying ice off its roof, stay back! I didn't stay back far enough. I saw ice flying off the truck's roof, but I only saw small pieces, not the 1 and a half foot wide monster piece that broke the windshield.
