Whetstone Brook cuts through West Brattleboro in a notch, and the yards above it are all angle, terrace and stone wall. Conner Hamilton Landscaping & Firewood LLC mows that kind of ground — the pitched side lawns, the one flat patch by the door, the strip along the road that everybody sees. Come late October the oaks and maples on the slope let go and the fall cleanup turns serious: rakes, blowers, and a full load hauled away. Then the grass gets one last low cut before the cold settles in for good. It is a good feeling to leave a hillside yard bare and orderly with the ridge going bronze behind it.
