Friday night into Saturday morning, DC had a wintry mix of snow, sleet and freezing rain. As it turned out there was not much accumulation. I went out later in the afternoon to do a little shopping. I encountered the usual idiots out on the road. These are the people who refuse to clean off their entire car of snow.
Thus on several occasion large chunks of the wintry mix flew off cars. In once case I'm taking about something three to four feet square. Thankfully these didn't land directly on any car. I've never understood why someone can't take the extra five minutes or so and clear off their entire car.
