Early Saturday, dew still sitting on everything, and the first mower of the day starts up somewhere near Beardsley Park. JJ's Lawn Services keeps that appointment right through the growing months in Champaign — mowing, trimming the tight spots a deck can't reach, edging the drives and walks, and clearing away what falls in spring and again in autumn. Grass in this town comes up thick and comes up fast, and a yard left a week too long takes twice the work to put back. The remedy is simple and old: steady visits, sharp blades, an eye on what the sky is doing. A finished lawn on a still summer morning is one of the plain pleasures of ordinary life.
