Below the dam the Quinebaug runs cold even in July, and the yards on the roads above it green up and stay that way. Thompson Lawn Care mows them on a set week, trims what the mower cannot reach, edges the hard lines along drives and walks, and does the cleanups that open spring and shut down fall. Midsummer the work is heat, dust, and the smell of a full grass bag at the end of a row. The look to hit is uncomplicated: even height, clean borders, nothing left scattered on the walk. That is a lawn in Thompson done the way a Thompson lawn should be.
