Four Mile Road climbs out of Glenwood Springs toward Sunlight, and in January it collects snow the way a gutter collects rain — steadily, then all at once. All Seasons Property Services Colorado runs the plow up those grades in the blue hour, when the only other light is a kitchen window and the sanded track behind the truck. By June the same road is all irrigation hiss and cut grass, and the work turns to mowing, trimming and hauling off the winter's scatter of gravel and broken branch. It is one property, watched twice: white in the dark months, green in the long ones. The reward is plain enough — a driveway a family can leave by seven in the morning, and a lawn they can sit on by seven at night.
