By seven on a July morning Devils Lake is still glass, the mist lifting off it, and the lawns above the shore are heavy with dew. Fleabay Lawn Care starts about then, mowing and trimming the yards on the slopes around Onsted while the day is still cool enough to enjoy. Grass on kettle-hill ground grows unevenly — full sun on one side, oak shade on the other — so it gets cut with an eye on both. Trimming, edging, spring and fall cleanups, and leaves cleared off the drives before the rain glues them down. By evening the yard looks like somebody meant it.
