Some of us have had some very strange winters with wild temperature swings between unseasonably warm, and then sudden drops to very cold and back again. Maybe it's like that where you live. Out of those rapid changes come some less than fun driving conditions like black ice, for example. There's a snowstorm or ice storm one day, and then it's warm enough the next day to start melting much or most of that frozen stuff. Then it gets cold again at night, and what thawed during the day freezes at night, sometimes into this dark, invisible ice patch on the street - that's black ice. And invariably you turn on the traffic report and you hear about a rash of accidents often from cars or trucks speeding along at top speed down the pavement that appeared to be totally dry. Then, out of nowhere, they find themselves sliding on one of those deadly little frozen spots.
