Down at Milton Lower Mills the Neponset drops over the old dam and the brick of the chocolate mill goes copper in the last hour of light. Andrew Thomas & Sons Landscaping keeps the lawns on the streets that climb away from that water — a steady mowing route, trimming close to fence posts and granite steps, leaves hauled off in fall so the grass goes into the cold breathing. There is pride in a yard that looks finished rather than merely cut. Stripes that run true to the sidewalk. Beds edged so the mulch line reads like a drawn border.
