Early on a Rye morning, with the fog still lying low over the salt marsh and the light coming up gray-gold off the Atlantic, the mowers come off the trailer. O'Neill Landscaping, Inc. is a lawn care and snow removal outfit working Rye and the neighboring Seacoast towns of New Hampshire — grass cut and tended through the green months, driveways plowed and cleared when the wind turns hard and northeast. There is a plain, lasting satisfaction in a lawn trimmed clean to the foot of an old stone wall, and in a drive opened down to the pavement before anyone has to leave for work. Salt air asks a lot of a yard out here, and the answer is simply the return: week after week, storm after storm, until a place looks looked-after from the road.
