Out at Berkey, near the Michigan line, the Oak Openings sand ridges run underneath everything — light soil, big oaks, and countryside that drains faster than the rest of Lucas County. Nil Gallagher Inc mows on that sand: cutting a notch higher when July turns dry, trimming the fence lines, edging the drives, opening the beds spring and fall. Wind crosses the savanna and pulls the moisture out of a lawn by noon, so timing a cut matters nearly as much as making it. When the oaks finally let go in autumn, the leaf work follows the same route through town. Grass that suits the ground it grows in — that is the goal out here.
