The Battenkill runs cold and quick past Cambridge, and the valley greens early because of it. Care Fox Enterprises keeps that green in order through the warm months with mowing on a schedule, trimming and edging the lines a lawn needs to look intentional, and the cleanups that open the yards in spring and close them in November. When the valley turns and the first storm comes down off the hills, the same trucks go to plowing driveways, farm lanes and lots, with salt on the steep spots. Two seasons, one property, one crew that knows where every culvert and gatepost is hiding. That knowledge is most of the job.
