On a July evening the light comes in low across Lake Winnemaug and lies flat over the yards on the roads above it, and that is the hour when mowing lines show — the alternating stripes, the edge held true the length of a walkway. GET GOOD Lawn Care LLC works toward that view: regular mowing, string trimming, crisp edging, and cleanups in spring and fall when a yard needs putting back in order. The ground around here is hilly and full of stone, so a straight line is something earned rather than found. Come winter the same trucks are out plowing, shoveling and salting, opening driveways and lots before anyone's day begins. Homes and small yards around Watertown, Oakville and the roads that lead out of them.
