When you live above the 40th parallel and you don't have a garage to keep your car in during the winter, you may find yourself driving around with an 8 inch thick slab of snow on the hood of your vehicle.
I thought that it was starting to snow while driving down the highway, but it was only coming from the giant snow mattress on top of the car in front of me.
