Its raining outside. Make that pouring. If it were still as cold as it was two days ago, it would be about 6 feet deep. Which has me thinking about shoveling. I have seen many beautiful walkways ruined with salts and in my own case, my front porch is ipe wood, which I fear to damage with a shovel. These Heat Trak stair mats will to do the trick. And they operate for a mere $0.15 an hour.
