Dobbs Ferry runs downhill to the Hudson, and the light bouncing back off the water in late afternoon makes even a small front lawn look like something. A. Vulpone Landscaping keeps those village yards going — mowing, trimming, edging along slate walks and short steep driveways, mulch in the beds each spring. The Old Croton Aqueduct path threads through town beneath big old trees, which means shade lawns, root-bound corners and a great deal of leaf work come November. Cleanups in spring and fall bracket a growing season that starts early down here by the river. Across the water the Palisades change color all day long; underfoot, the grass just needs cutting on time.
