Morning on the south arm of Lake Charlevoix comes in flat and silver, and by the time the water picks up its first wind, B&W nature's maintenance is already working the lawns above it. This is mowing, trimming and edging in East Jordan, where the Jordan River lets go of its valley and the town leans down to meet the lake. Grass grows fast on river-bottom air, so the schedule keeps its own rhythm: cut, edge, blow the clippings back off the walk, move on. Spring and fall cleanups clear what the maples and the wind leave behind on the hill streets. The reward is small and exact — a lawn that reads as one clean shape from the road, with the line at the driveway drawn like it was ruled.
