Land is the word Vineland has always turned on — acres of it, laid out in straight lines by a founder with a plan, still growing something. J P Land Enterprises LLC keeps the domestic version in shape: mowing on a set week, edging along drives and walkways, trimming out the corners a deck cannot reach, cleanups in spring and fall. Out past Panther Road the properties open up and the mowing runs long and quiet. In the closer neighborhoods it is a tighter job — more turning, more trimming, the same finish. Either way the lawn is left with its lines showing.
