The Town River runs slow and green under the bridges at the center of Bridgewater, and the lawns along its banks wake up early. Freedom Lawn Care works those yards through the growing months, mowing, edging and trimming back whatever a wet spring pushed too far. There is a particular satisfaction in the last pass of the day, when the stripes line up and the edge along a walk reads like a drawn line. Cleanups come in spring and again when the oaks let go in October. It is ordinary work in a town of flat green and old stone, done so a yard looks cared for from the street.
