I hit one of these getting my mail late at night. Pretty sobering knowing I'd have been dead in 30 minutes due to the temperature and no one would have likely been by to check because it was late. They can stick around even after most of the snow/ice has melted because of shadows that never allow sunlight to hit a particular spot.
