A Tuesday in Warren Park sounds like a sprinkler, a screen door, and one mower going up and back across a lawn twenty-five feet wide. John krohn lawncare keeps to that register — mowing, trimming around the posts and the hydrant, edging the walk, sweeping the clippings off the concrete before moving on. Midsummer in Cicero turns thick and bright by nine in the morning, so the early rounds get the easy air and the shade side waits until last. Cleanups at both ends of the season keep the parkways and corners clear. A neat yard on an ordinary street is a small thing, and it holds up the whole block.
