On a July morning the mist lifts off Kezar Lake and hangs in the birches until the sun clears the ridge. Fieldstone Landscaping mows and trims the lawns that run down toward that shoreline, keeping the grass short enough for bare feet and the beds edged clean where lawn meets garden. Weekly cutting, trimming, edging, a spring wake-up and the fall leaf work — that is the rhythm that keeps a Lovell summer looking the way people picture it all winter. Clippings get cleared off walks and drives rather than tracked indoors. A lawn cut and lined out with the lake behind it is much of the reason people come north at all.
