Nice symmetry: in the summer it's the drone of lawn mowers up and down the street; in winter it's the growl of snowblowers. You can look up the street and see rooster tails of snow flinging themselves into the air. Kinda like the United Airlines commercials in Chicago a few years ago, with the drawbridges over the river going up and down in stutter-step synchronization. Smells a bit different though - as bad as the river can be, it doesn't reek of 2-cycle engines.
