You can hear the Black River working over the dam in the middle of Dexter, a sound this village has mowed its lawns to for a long while. A&F LawnCare keeps that rhythm going — even passes, tidy turns, string trimming around the maples and the old stone foundations. A yard finished in the afternoon holds its lines until the dew comes in. Cleanups come in their turn, spring and fall, clearing whatever the wind off the water leaves behind. Lawn care for a mill village where the river never stops and the grass never asks permission.
