Every spring the herring run up the Mattapoisett River beneath the Route 6 bridge, and the town takes it as the sign that the season has genuinely begun. Langlois Landscapes LLC starts about then too — spring cleanup first, then mowing, trimming and edging on a steady rotation until the last leaves come down. Winter reverses all of it: plowing driveways and lots, cutting walkways clear, going back out again when the wind fills them in. A yard kept all summer and a driveway opened at six on a February morning are the same promise made in two different languages. Mattapoisett gets both.
