The Kalamazoo River loops through Marengo Township on its way past Marshall, and the bottomland along it greens up before anything else in Calhoun County. Black Pine Services LLC mows those river-flat yards and the ones up on the rise where the wind finds you, trimming and edging so each lawn reads clean from the road. Midsummer is the long stretch — weekly cuts, the trimmer around fenceposts and mailbox, the blower over the drive before pulling out. Cleanups in spring and fall stretch the season out at both ends, moving leaves and winter litter off the turf. There is something plain and good about leaving a place tidier than it was an hour before.
