There is a particular green that Woonsocket gets in early June, the kind you see on the ballfields at Cass Park when the grass has been cut and the lines are fresh. Don's Lawn Care, LLC chases that green across the city's yards — weekly mowing, trimming, edging, mulching, hedge shaping and the cleanups that bracket the season at both ends. Most lots here are modest and hemmed by fence and driveway, which makes the neat pass and the clean corner matter more, not less. A lawn that looks cared for changes the whole face of a house, and that is the point of the trip. Same yards, same day of the week, all season long.
