Noon in Thomaston, and the tower on the Opera House marks the hour over a town that once measured them out for everybody else. Clocktown Landscape works the short streets that step up from the Naugatuck — mowing, trimming, edging, bed care and mulch on lots that are rarely square and often steep. Small-town yards reward attention: a tidy strip between sidewalk and street, a hedge line held true, grass taken down before the heat sets into the afternoon. Autumn brings the leaf work, most of it coming off the hill at once. It is ordinary maintenance, and it changes how a whole street reads.
