The courthouse square holds the middle of Louisville, and the grass around a town like this tells you exactly what kind of summer it has been. Lawn Nerds mows, trims and edges on a schedule you can set a clock by. Straight lines. Clean corners. Nothing left on the walk when the blower shuts off. Yards here run wide and flat toward the field lines, and a wide flat yard is unforgiving — every missed pass shows — which is precisely why the passes do not get missed. Cleanups in spring and fall bracket the season on both ends.
