After two days of constant snowfall, Montreal starts to dig out. Snow must be removed, not just set aside, so it is scooped up and trucked out. There's a whole line of trucks waiting to be filled! You who live in snowy climates may think this is old hat, but it's fascinating to those of us who live in more temperate zones. -via reddit
I lived in Denver for many years and in the metro area you are fined if the snow isn't removed from the sidewalk in front of your house.
Personally I love snow so it has never bothered me to shovel the drive or the walk.
