Snow Baffeled

So I don't know how they do it, but somehow people manage to keep all this snow off their driveways. Kory and I have no such luck. We have tried, but no matter what, we still get a layer of ice, and snow on our walks. We even tried the ice melt stuff, and it did nothing. I just want to know if there is some sort of trick we don't know about. If anyone has some suggestions, please let us know.
