South of downtown the Fox takes a long bend toward North Aurora, and the streets above it fill up on Saturday with mowers, sprinklers and somebody's radio two yards over. Riddle Lawn Care and Pressure Washing is in that mix, cutting, trimming and edging Batavia lawns on a weekly rhythm through the growing months. Summer here is humid and green and generous, which is another way of saying the grass never entirely stops. Getting it right means even height, a clean line at the walk, and clippings off the concrete before anyone leaves. The finished yard is the whole argument.
