Off Dukes County Avenue the lots sit close together and the hedges do most of the fencing, so every square of lawn counts for more simply because there is less of it. Shirley Lawn Care Services works those Oak Bluffs yards with the attention small spaces ask for — mowing without scalping the corners, trimming clean around posts and steps, edging the walk, and clearing spring and fall debris out of the tight places. Down by Niantic Park the summer sound is the basketball court; a street or two up, it is a mower finishing a lawn. Neat grass in a close neighborhood reads plainly as care, no explanation needed. That is what all of it is for.
