Fog pools in the Otisco valley on May mornings and burns off around nine, leaving the Marietta lawns steaming in the new sun. Carroll Landscape & Tree Service LLC mows the hill yards and the lots above the lake, trims the edges back tight, clears the beds and carries off the brush that the hardwoods shed all winter. Cutting a slope well is its own skill — the deck held level, the stripes running with the hill rather than against it. Come late October the leaves come down all at once off the ridge and the season closes with a thorough raking. Marcellus, Otisco, Borodino and Skaneateles are all a few minutes over the hill.
