In June the village by the opera house wakes early — river fog off the Connecticut first, then a bright hard morning. Watkins landscaping LLC is out in it, mowing, trimming, edging walks and drives, laying mulch and running the spring and fall cleanups. Old river-town lots come with stone walls, strange angles and trees planted long before anyone owned a mower, which makes a neat finish a small victory every time. The stripes on a level lawn near the water hold their line the whole week through. That is the part worth doing carefully.
