On the blocks near Exchange Street the yards are old and generous, with room enough for a mower to stretch out and lay down a straight line. Bladespinners Lawn Service keeps them cut through the long green middle of an Illinois summer, the stretch when two warm rains in a week will put an inch of growth on everything. The work is mowing, trimming and edging, week after week, plus the cleanups that bracket the season at either end. Done right, a lawn reads as one plane of color from the sidewalk to the back fence, with the trim lines around posts and beds as tidy as the open ground. That is the whole ambition here, repeated across Crete every week the grass is growing.
