Sanbornton is a town of ridges: the roads climb and drop, and every so often the trees open on a blue slice of Winnisquam far below. Keenan Tree Care, LLC keeps lawns on those hillsides — the ones that never sit level, where a mower has to be worked with your weight on the uphill side. Summer mornings up here start cool even in July, and the grass cuts sweet before the heat arrives. Trimming around old fieldstone, edging a walk, clearing what the season has dropped on a slope — it adds up to a property that looks tended from the town road. That view down to the lake deserves a foreground worth looking at.
