The big lots on the north end of Champaign — Marketview, the frontage roads, the places that have to open at seven no matter what the sky did overnight — need a different kind of work than a driveway does. Atlantic Services Inc plows and salts at that scale, stacking snow in the corners where it will not blind a turning driver and treating the lanes before the afternoon melt refreezes at dusk. Out here the wind has nothing to slow it between the interstate and the parking lines, so drifts rebuild themselves and the route gets run a second time. There is a particular pleasure in a lot that looks like nothing ever happened to it. That invisibility is the craft.
