Just got in from shoveling an inch of wet slop from my neighbors and my sidewalks in the sleet. Better to be safe than cursing in the am that it froze . I only trust 2 people myself and the weatherman isn't the second.
You can't hear them, they can't hear you. Just have to watch for movement. By now you should know the direction they will be coming from, and approx. time. Move your eyes not you head. GL. wish I still had that problem.
