Some storms come down out of the northwest with no warmth in them at all, crossing the Iowa fields and reaching Rock Island as fine dry snow that blows for hours. Quad City Lawn and Landscape works that weather, plowing driveways and lots, shoveling walks and steps, spreading salt where wind-packed snow has turned into a sheet. Buses run early here, and that sets the deadline. Nothing about it is complicated; it is showing up in the dark and making as many passes as the storm actually takes. By breakfast the property is open again.
