North of the city the roads run straight between stands of pine toward Twin Lake, and in January the dusk arrives at five o'clock with snow already in it. Ladon Irrigation LLC works those winter miles for Muskegon, plowing driveways and clearing walks so a porch light has something to shine on besides a drift. Country drives ask for patience: they run long, they close at the open field, and they have to be pushed back far enough that the next storm has somewhere to go. Ice treatment goes down where a slope meets the road, because that is the ten feet that matters. When the headlights swing out again, the drive behind is a dark clean ribbon under falling snow.
