Twice a day the Weskeag runs backward under the bridge at South Thomaston, and the marsh grass lies down with the tide. Benner's Tree Services works the properties along that water — mowing the river lots and the fields above the marsh, trimming the edges where the alders crowd in, clearing away what the wind brought down overnight. When winter shuts the tide in ice, the truck heads out on the Keag roads with the plow, opening driveways and long camp roads and clearing the paths behind them. Standing at the end of a finished drive with the salt air sharp in your throat, knowing the place is passable again, is a fine way to start a morning. Lawn care and snow removal along the Weskeag.
