Down where the Little River slides into the salt marsh near Parsons Beach, October turns the grass to copper and the evenings show up an hour ahead of schedule. Peace of Mind Landscape Construction Inc. spends that light closing the mowing year cleanly — final cuts, beds squared, leaves lifted off the turf before frost pins them there. Then the gear changes and the winter list begins: plowing driveways, opening lots, clearing walks so nobody has to guess where the step is. Two trades, one rhythm, both about handing a property back in better shape than the weather left it. In Kennebunk that is a conversation with the sky that never quite ends.
