The first real snow along Eleven Mile usually arrives in the night, and Warren wakes to a city gone soft-edged and hushed for a few hours. Zettner's lawn and snow removal LLC is already out in it — plowing driveways and lots, clearing walks and steps, salting the low spots where meltwater will refreeze by evening. Come April the trucks trade blades for mowers, and those same properties get mowing, trimming, edging and the cleanup that pulls the season's wreckage off the lawn. The two halves rhyme more than people expect: show up early, take the mess away, leave a clear surface behind. In this city that is a year-round job.
