Toward the Salem line the ground turns stubborn — ledge shouldering up through the soil above Spring Pond, thin lawns lying on top of it. E&E Lawn & Landscape mows that kind of terrain the way it has to be mowed, reading the pitch and the rock rather than fighting them. Weekly cuts carry the summer, with trimming worked in close around outcrops and stone walls and a run of edging where turf meets asphalt. The spring pass pulls out road sand and the winter's broken twigs; the fall pass takes the oak leaves, which come down late and heavy on this side of the city. The lawns finish even and green in a place that does not hand that over easily.
