Sprout Brook still runs its old line through Paramus, mostly out of sight now behind hedgerows and back fences, and in August the ground near it stays green when everything else has gone tired. NL Tree Services, Inc. keeps the lawns above it cut, edged, and trimmed through that heat, with the cleanups that bracket the growing season at either end. When December closes the ground, the work shifts over to plowing driveways, opening walkways, and salting the ice out of the way. Two very different kinds of early morning, the same properties, the same borough. The through-line is a place that plainly looks looked-after.
