By nine at night a Grand Rapids snowfall has already changed the shape of every street off Fulton — curbs gone, corners rounded, the streetlights hazed over. That is when Seif Lawn Care & Snow Plowing goes to work, running driveways and walks around Ottawa Hills and Garfield Park while the city is indoors. Plowing, shoveling the paths people actually use, treating the aprons where meltwater will freeze by three in the morning. The best compliment this job gets is silence: nobody calls, because there was nothing to call about. Then the sun comes up on dark, dry pavement and the trucks go home.
