East of town the streets give out into Lakes Bay, where the tide walks up the ditches twice a day and the water turns the color of pewter ahead of weather. Bayside Lawn Care LLC works those flat, wind-scoured yards — mowing on a rhythm the grass can count on, trimming around fence posts and bulkheads, edging until the lawn stops exactly where it is supposed to. Salt wind is hard on turf this close to the water, so the height of the cut matters, and so does clearing out whatever the wind piles into the corners. On a still evening after a mow, with the marsh going pink behind the rooftops, a Pleasantville yard looks like it has been put in order. That is the point of the whole day.
