Lunenburg keeps its old shape — stone walls running off into the woods, fields sloping down toward Massapoag Pond, a common that looks its finest the week the maples turn. Ray Morin Inc works that landscape all year, mowing, trimming and edging through the growing months and plowing driveways, shoveling walks and salting steps once the cold sets in. Spring and fall cleanups carry off what each end of the year leaves behind: sand and broken branches in April, a deep drift of leaves in November. On a wide Lunenburg lot, a clean mow line running along a stone wall is a quietly beautiful thing and worth the extra pass. The same goes for a driveway plowed square to its edges at dawn.
