We had light snow here (Bend, OR) yesterday -- less than half an inch on the ground...but overnight we got freezing rain.
My [parked-outside] car this morning had a glaze of ice maybe 1/8 inch thick, as did my front steps and everything else. Fortunately for me I had nowhere to go until 10 am, and by that time the sunshine had broken the freeze. Car was still ice covered, but the ice slid off easily with application of scraper. My little-traveled and shady neighborhood road, however, was very slick -- the slightest application of brakes activated ABS as I made my way out...
