On a June morning by Hessian Lake the mist lifts off the water and the mountain laurel is still holding its bloom. Moe's Lawncare is already at work below the ridge, mowing lawns that sit in pockets of sun between oak stands and outcrops of granite. The trimmer handles everything the mower cannot — the strip beside a stone step, the bank behind a shed, the ring around a birch. Grass grows in fits up here depending on shade, so the schedule bends to the yard rather than to the calendar. Cleanups bracket the year at both ends, and each visit finishes with the walks blown clean.
