Three in the morning, a hundred yards of farm driveway, and nothing out there but headlights and falling snow — that is the shift. HOSS BROTHERS plows the long rural drives and the short town ones around Greenville, clears walks down to the pavement, and salts where meltwater runs and refreezes. Montcalm County roads drift wherever the fields open to the west, so one driveway can need two visits before breakfast. They go back. Morning comes and everybody gets out.
