West of downtown Sanford the land flattens out around the airport, and wind crosses it with nothing at all to slow it down. That is where a March storm shows its teeth, filling a driveway back in twice before breakfast, and where Northwoods property services, LLC keeps plowing — pass after pass, until the pavement is honestly clear rather than merely passable. In summer that same open ground grows fast, and the mowing and trimming keep pace with it week by week. Work on exposed property rewards stubbornness more than anything else, and a wide, wind-scoured driveway is its own kind of proof. Sanford and the open country west of it, out toward Acton and Lebanon, make up the run.
