Marcus Hook sits at the bend of the Delaware where Pennsylvania runs down to the state line, and a year here stacks two trades into one truck. Spring and summer belong to the mower and the bed spade — grass cut to an even height, borders edged, mulch laid dark around the shrubs. Then the light shortens, the wind turns metallic off the water, and a blade goes on the front for plowing driveways and salting the walks that glaze first. Buck's Lawn Care and Landscaping works both halves for the same streets, so the yard that was tidy in July is the drive that's open in February. Marcus Hook, Boothwyn, Trainer and the blocks running toward Claymont are the ground it covers.
