South of Chatsworth the land folds down toward Carters Lake, and by Friday afternoon half the county is thinking about water instead of weeds. Keller Outdoor Inc gets out ahead of that — mowing, trimming, edging and yard cleanup timed so a property is finished before the weekend arrives. There's a particular pleasure in pulling out of a drive on a Friday with nothing left undone behind you. The cut is still fresh, the concrete is swept, the hedge line is tight. Whatever the owner does with their Saturday, the yard is not on the list.
