Saturday morning in Cicero, dew still on everything, and the mowers start up one street after another. J.S. Lawns is out in that early hour cutting, trimming and edging yards on the neighborhood blocks between the highway and the open fields. The work is unglamorous and exact: even height, clear borders, clippings swept off the walk before the job is called done. A lawn done right never announces itself, it simply looks calm, and the whole house reads better for it. From the first green week to the final mow, that is what is on offer here.
