West Michigan afternoons in July build their storms out over Lake Michigan and send them inland with about an hour's warning. Jumps Lawn Care reads that sky for a living, mowing, trimming and edging Byron Center lawns between the heat and the rain, then circling back once the wind has stripped the silver maples. Grass grows fastest in the muggy stretch when nobody wants to be outdoors, which is exactly when a yard most needs someone who is. The reward is small and real: a lawn cut clean at six o'clock, steaming a little, striped and quiet. Autumn brings the rakes, and the season closes as neatly as it opened.
