Late August, and the marsh at the edge of Lake Skegemog is loud with insects while a heron works the shallows like it has all day. Nienhouse Outdoors mows the lawns that back up to that low green country in Whitewater Township, where the ground stays damp and the grass keeps pushing long after everyone else's has slowed. The cut is kept even, the trimmer is taken around every fence post and dock post, and the clippings are cleared off the walk so the yard reads finished from the road. Fall brings leaves, and plenty of them, gathered before they can pack down over the turf. It is outdoor work in a place that rewards paying attention.
