Dewittville sits where the hills ease down to the northern end of Chautauqua Lake, and everything here takes its cue from that water. In summer, Paterniti Property Maintenance mows the long lake-facing lawns, edging the walks so the border between grass and stone stays one clean line all the way toward the shore. Then the lake gives back what it took: bands of snow that set up in November and do not really quit. Plow work starts before daylight — drives opened, turnarounds widened, paths cut to the door while the flakes are still stacking. One outfit for both halves of a Chautauqua County year.
