    "Kelly Andrew, the crew supervisor in charge of the plows, has a farming background. He said he's watched farmers use a similar technique to clear snow from fields. .... 'It looked like it melted about twice as fast as the snow without the material on it,' Andrew said. .... 'It collects that solar heat, and Mother Nature does her thing with that black surface,' Saunders said."


    Terrific idea! I'm astonished it hadn't been done before.

    Apparently like farmers, the principle of something dark (the sand) rather than stark white (the snow) collecting more solar energy and thus melting the snow more quickly is the basis of a strategy I've used in clearing my sidewalks and driveway for decades.
