A freight rolls through Bound Brook at midday and the whole block hums for half a minute, then goes back to September quiet. Rivera Brothers Landscaping is out in it, still mowing — the grass slows in early fall but it does not stop, and the cuts stay on schedule. Trimming keeps the fence lines sharp, edging keeps the walks defined, and the lawn is cleared off before the trailer gate goes back up. Once the leaves start, the work turns to pulling them out of the beds and off the grass. The last cut of the season is the one that carries a yard through winter.
