Fog comes off the Chadakoin first thing, softening the riverside blocks until the sun works through it. Arrowwood Landscaping runs the mowers into that green stretch between thaw and leaf-fall, cutting, trimming and edging the yards that sit on Jamestown's old bottom ground where grass comes back fast and thick. There is a real satisfaction in the last pass beside a walk, when the edge lifts up clean as a ruled line. In winter the trailers give way to plow blades: driveways opened, walks cleared, salt down before anyone reaches for a car door. Two kinds of work, one idea behind both of them.
