The Rifle River bends through Sterling on its way to Saginaw Bay, quick and tea-colored in July, iced along its edges by December. Pro-Scape Landscaping & Maintenance, Inc works Arenac County on that same swing — grass cut and borders kept while the river is full of tubers, then plowing out drives and treating the ice when the wind comes across the flats from the bay. Winter here is open-country snow: it drifts, it fills back in, and clearing the same driveway twice in one night is nothing unusual. Summer work is steadier, a weekly rotation with the lines held true along walks and drives. The river sets the pace either way.
