The ferry still crosses the Connecticut at Glastonbury, and on a still July morning the river throws its light back up the bank into the yards above. Sanderson Seasonal Services works that riverside stretch and the neighborhoods behind it — weekly mowing, edges run straight along drives and walks, trimming close around fence posts and foundations. Spring means raking out everything winter left behind; fall means leaves gathered and carried off before they smother the turf. A lawn kept on a schedule stops feeling like a chore and starts reading like a room. Glastonbury and the towns bordering it are the whole territory.
