South of the village the land flattens into the Katama plain, and the wind crossing it has come straight off South Beach with salt still in it. Grass out here earns its green. Crossland Landscape Inc works that open ground with mowing, edging, string trimming and the cleanups that open and close the growing year. There is a particular satisfaction in a lawn cut clean against sandy soil and a sea breeze — stripes holding straight, borders drawn true. From the plain back up into Edgartown's shaded lanes, the aim doesn't change: leave every yard sharper than you found it.
