Some mornings the Fox River sends fog up over Walton Island and the whole downtown stays soft at the edges until nine o'clock. Mystic Lawn Care starts in that gray hour, dew still heavy, the first cut of the day leaving a dark wet track behind the mower. By noon the grass has dried and the lines stand up sharp across the yard. Trimming, edging and a clean sweep of the drive finish it off. Coming home to a lawn tended while you were gone is a small, good thing.
