Northwest Arkansas hands out its weather fast: a June morning in Rogers can be still and blue at seven and full of thunder by four. J and N Mowing and More, LLC starts early for that reason, running the route while the grass is dry — mowing, string trimming around posts and stone, edging the sidewalks, sweeping the concrete clear afterward. Yards here roll with the ground, and a hillside lot mows nothing like the flat one beside it. Done well, the cut follows the slope instead of fighting it and the lines come out honest. It is ordinary work, and this valley looks better for it.
