Saturday morning in Canarsie: gulls turning over Paerdegat Basin, someone's radio through a screen window, mowers starting up one after another down the block. Chris's Lawn Service LLC is one of them, cutting front and back lawns to an even height, running the trimmer along fence posts and the seam of the driveway. Autumn brings the leaves and April brings the cleanup, and in between it's the steady rhythm of grass kept short. The pier is ten minutes off and the day is still wide open by the time the last yard is done. Mowing and seasonal yard work in Brooklyn.
