South Dennis lies where the cedar water of Dennis Creek slides out through the salt hay toward the Delaware Bay, and the sunsets there go on for half an hour. Coastland Landscaping LLC keeps lawns along those back roads — big open yards, sandy Cape May County ground, grass that asks for mowing right through a long warm season. Winter here is mostly wind, but when snow does come across the bay it comes fast, and driveways set far back from Route 47 need opening before anyone can get out. The crew works both ends of the calendar the same way: level cuts in August, clear pavement in January. The marsh changes color behind them either way.
