Down at the riverfront the grass along the walk comes up tall and lush in July, fed by every thunderstorm that rolls up the valley. Mostly Mowing CT does what the name says and a little besides — weekly mowing, string trimming, edging along drives and walks, and cleanups as the season opens and closes. Town lots here sit close together, so a straight line matters and so does keeping the clippings off the neighbor's walk. The reward is a whole street of yards that look like they belong to one another. Plain work, done carefully, with the results sitting right out front where anybody can see them.
