Snow reaches Northfield off the water heavy and wet, and it usually finishes falling somewhere in the middle of the night. Grasso Landscaping is out in the dark behind it, headlights swinging up Zion Road, pushing driveways back to the blacktop and cutting a clear path to every front door before the first cars leave for work. Salt goes down where the shade keeps ice stubborn. The rest of the year those same trucks carry mowers, and the work turns to weekly cutting, trimmed fence lines and edges struck sharp along the curb. Two seasons, one idea: make the ground do what it ought to.
