Gah, I hate it when people are too fucking lazy to shovel their sidewalks or just do a small narrow path instead of the whole sidewalk. While I haven't had to shovel anything since 1994 (other than a one-off this past Christmas at my mom's place), I have put in more than my fair share when I lived at home...on a corner lot... So I know all about the pains of shovelling. Buy an ergonomic shovel, buy a snowblower, borrow a snowblower, hire a company or a neighbourhood kid to move the snow, do something at least.
