Winter here often arrives as rain that changes its mind — a glaze on the steps, sycamore branches ticking in the dark. American Clean Care & Lawn Care LLC treats that kind of night as the job: plow the drive, clear the walk down to pavement, and put salt where the sun will not reach until noon. Ice does its worst on the north side of a house, and knowing that is half the work. By the time the neighborhood is stirring, the driveway is a black rectangle and the path to the door is safe to walk in ordinary shoes. Centreville, Cahokia Heights and the nearby river towns make up the winter territory.
