Out toward Crooked River the marsh keeps its own calendar, the tide sliding up through the spartina and back out twice a day while the yards along the bluff go about their growing. Jenn's Lawncare runs the ordinary rounds there — mowing, trimming, edging, leaf and limb cleanup — on the weekly rhythm a Camden County summer demands. Salt wind, sandy soil and long heat make coastal turf a particular animal, generous when it is watched and stubborn when it is not. What keeps it interesting is arriving at a yard gone shaggy and leaving it composed, the creek glinting past the fence. St. Marys and the roads nearby keep that circuit full.
