North of town the subdivisions thin out and the lots get generous — half acres and better, backing onto farm ground toward Casco, where the grass goes shaggy fast in an August week of heat and thunderstorms. Grizzly Grounds LLC is built for that kind of ground: the wide open cut, the rough back corners, the ditch line and the fence row that a small mower can't reach. Big properties reward patience, and there's a specific pleasure in the last pass, when the whole field of it finally reads as one lawn again. Then a walk-around with the trimmer to square up the edges and it's done. They mow across New Baltimore and out into the surrounding townships.
