1. Do the width of the sidewalk; clearing a foot-wide path is lazy - it's hard to walk and strollers are screwed. 2. If you live on a corner, do out to the street. Why should people have to negotiate a mountain next to your house? 3. If you go south for the winter, contract someone to keep your walks clear. You might not be here, but the rest of us are. C'mon people, just because you might never walk on your own sidewalks, think about your neighbors.
