North Linn lies in steep Ozark country, where the hills fold into deep hollows and cedar glades open on the rocky south-facing slopes. In late May the thunderheads pile up over the ridges on many afternoons, and between storms the grass grows lush and fast. COBA Lawn & Landscape LLC keeps yards in shape across this terrain, mowing hillside lawns that tilt hard toward the hollow and tending landscape beds tucked against rock outcrops. A tidy yard here is a small clearing of order in a wild and beautiful landscape, and it looks all the more striking for the woods crowding close around it.
