August in Berwick keeps a long gold hour at the end of it, when the heat lets go and the maple shadows stretch clear across the yard. That is Cantwell Outdoor Services' favorite time to make a last pass — mower, trimmer, blower, then a look back down the lawn to see it whole. They keep grass cut on a rhythm all growing season, hold the edges where beds meet turf, and haul the leaves off in autumn when the ridge above town goes copper. Nothing elaborate is being described here, just a yard that greets you when you pull in. Berwick and its neighbors on both sides of the river get the same steady attention.
