Freight still comes through Cornelia at dusk, and the sound of it carries the same over parking lots as over long grass verges. Courageous Grounds Management LLC keeps the bigger properties in order — acreage mowed, string-line edges cut, debris cleared, entrances and islands kept open for whoever arrives in the morning. Most of the work is finished before anyone notices it was needed, which is the shape of grounds work done right. Leaves in November, the growth flush of May, the long green middle of a Georgia summer: each gets its own pace. A property that always looks handled is the entire point.
