On Plymouth Hill the leaves turn early and go all at once, and for a few weeks in October the roads up toward Mount Tobe run copper from shoulder to shoulder. N&OUT LAWNCARE SERVICE LLC keeps lawns cut through the long green stretch that leads up to it, holding a yard even from the last frost of spring to the first of fall. Then the wind swings north, the hills lose their color, and the work becomes snow — drives and walks opened so a morning can start on time. Two seasons, one property, the same hands on both. It is a straightforward promise, and this town's weather gives it plenty of chances to be kept.
