Enfield Street runs a long straight mile of white clapboard and old shade, and in June the light comes through the leaves in pieces. CT Valley landscaping works underneath it — mowing, running the string trimmer along fence lines, edging the walks until the grass stops at a line you could have drawn with a ruler. Spring opens with a cleanup that hauls off everything winter left behind; fall closes with the leaves off the lawn before frost can set them in place. In between there is the steady rhythm of a yard kept, week after week, without drama. Few things flatter an Enfield house like the ground it stands on being taken seriously.
