Holy Snowballs Batman! It is seriously icky outside. My driveway has a 15 – 20 degree upward (or downward, depending on your perspective) slant. I was outside monkeying around with one vehicle, and I heard something that made me look toward the van. It was sliding down the driveway toward the street! It had been parked for at least a half an hour. The snow is just that greasy and slippery. I pulled the van ahead again, and I’m hoping the thing stays put overnight.
