Cobbs Hill fills up early on a summer morning — walkers circling the reservoir before the heat arrives — and the neighborhoods below it wake to the sound of mowers. Lawn Dawg is part of that sound: cutting, trimming, edging and clearing away what the cut leaves behind. Grass in July asks for a taller blade and a regular rhythm, and it pays that back in color. Nothing dresses a house faster than a lawn mowed on time and finished neatly at the curb. Streets around Culver Road and Winton Road, then out into Brighton and Pittsford, make up the route.
