Summer evenings on Drift Road make Westport's case for it: hayfields going amber, the light long and low, a breeze off the West Branch taking the edge off the day. G & S Landscaping is usually finishing somewhere in all that — mower loaded, trim work done, the last strip of a lawn cut with the sun almost in the way. Weekly mowing, string trimming, tidy beds and leaf work in November make up the warm half of the job. The cold half is a plow, a sander, and a driveway opened before breakfast. Westport, Dartmouth and down into Little Compton.
