South of Houlton the land opens out long and unhurried, potato ground rolling toward the treeline, and Nickerson Lake lying flat and bright in the middle of it. Potter's Property Services LLC works that country all the way around the calendar — mowing, trimming and edging yards through the green months, then plowing them back open when the drifts come across the fields. Aroostook winter arrives with room to run, and a wind-packed driveway at first light is a real piece of work to undo. There is satisfaction in the finished line: a drive squared off to the edge of the lawn, a walkway down to bare ground before the coffee cools. Linneus and its neighbors get the same attention in August that they get in January.
