There is an hour in February, well before the first train out of Upper Montclair, when the whole ridge is blue and silent and the driveways are still buried. R&S Landscaping & Property Maintenance is awake in it — plowing, shoveling walks down to bare pavement, salting the steep aprons that turn glassy wherever Montclair's grade meets a hard freeze. Come April the same properties want something gentler, and the trucks trade blades for mowers, trimmers and cleanup work straight through the growing season. Two very different jobs with one instinct behind both: get there early, leave the place usable. The reward on a snow night is the phone that never rings, because the driveway was already open at six.
