I was driving Youngest to my sister’s house to get on the bus today, and every time I turned or decelerated, my car made an awful grinding sound. Being me and therefore completely unconcerned about what my vehicle is doing as long as it is moving, I waited until I got to my sister’s driveway to look and see what was making the sound. I was just ice. Big chunks of dirty black ice, stuck in the wheel wells. When the car would move a little when I turned or slowed down quickly, it was just enough to scrape on the ice. Yay! No big mechanical problems!
