Morning fog off Buzzards Bay settles over the flat South End streets and holds until mid-morning, and then the whole city turns bright at once. The grass guy LLC is out working in it — mowing, trimming the tight corners, edging sidewalks so a lawn keeps its shape right through the growing season. Spring and fall cleanups do the heavy lifting at either end of the year: winter debris out in March, leaves cleared through October and November. Salt-air grass grows thick and quick in New Bedford, which makes a reliable weekly cut worth more than anything fancy. A lawn kept level all summer is a small daily pleasure.
