From the top of Upper Mountain Avenue the Manhattan skyline stands up out of the haze, and behind you the woods of Mills Reservation run on for a mile. Upper Mountain Landscaping keeps the lawns in between — mowing, edging, trimming, and the cleanups that ridge properties need when the reservation drops its leaves over the fence line. Lots up here tilt, and a slope changes everything about how you cut it and where the clippings end up. Late afternoon is the good hour: sun low behind the crest, a fresh-mown yard going gold on the high side and cool green on the low. Ordinary work with an extraordinary view, and both halves get taken seriously.
