Farmington Hills is laid out on a grid — Nine Mile up to Fourteen, Halsted across to Middlebelt — and on a snow morning that grid has to be drawn again by hand. Artistic Outdoor Services, Inc. is out in the blue hour, headlights swinging through falling flakes, blades laying down long clean lines where a driveway used to be. Walks get opened by shovel, and salt goes where the north side of a house keeps ice honest all day. There is a plain satisfaction in finishing a property while the sky is still dark and the pavement has gone black again under the lamps. By the time the first commuters back out, the morning looks easy — which is exactly the idea.
