Doing without a snowblower

We got about four inches of snow today. We have fifty feet of wide sidewalk, two sets of steps, about one hundred feet of narrow sidewalk, and a short two-car driveway. I shoveled all that in thirty minutes of light to moderate exercise, using only these two tools:  a snow scoop (aka "Yooper scooper") and a grain shovel. The snow scoop is a wide metal box, open at the front and top, with a handle for pushing. It enables me to clear wide areas quickly by pushing the snow, rather than lifting it. I've seen both homemade and commercial versions. The grain shovel (which can be found at farm supply stores) is very handy for steps and for heavy wet snow.
