Summer evenings around the Oak Ridge lakes run long and cool at the edges, and the lawns sloping down toward the water get more use in one weekend than most yards see in a month. GH Lawn Care LLC keeps those yards ready for it — mowing on a rhythm, trimming the fringe along stone and gravel, edging where lawn gives way to the drive. Lake-country grass grows unevenly, sun on one half and hemlock shade on the other, so a cut has to answer to both. Spring and fall cleanups take out the winter litter and then the autumn leaves. What's left is a lawn you can cross barefoot at dusk without thinking about it, which is the whole idea.
