Down where the Little Madawaska bends toward the Aroostook, August afternoons smell like cut hay and warm dust. Theriault Lawn Care carries that same smell through Caribou yards all summer — mowing on a regular round, trimming what the mower cannot reach, carrying off the clippings and, later, the leaves. Northern lawns get one good stretch of growing weather, and the aim is to make it look intentional the whole way through. A lawn cut on Friday holds its lines all weekend, and that is the point. Spring and autumn cleanups bracket the season on either end.
