Laconia sits on the narrow shelf of land where the Winnipesaukee River slips between two big lakes, and the old brick mills along its banks still set the shape of the streets that climb away toward the Belknaps. Dolloff Lawncare tends lawns in that landscape — mowing, trimming and edging, mulch beds, and the spring and fall cleanups that bracket a short northern growing season. There is a plain satisfaction in the result: the even passes laid across a yard tilting down toward the water, the clean line held along a granite walk, the raked border that makes an old house look looked-after again. The work runs through Laconia and the towns gathered around it in the Lakes Region, where the green weeks come in bright and brief and a yard has to make the most of its summer.
