Before the parking lots fill along the village's commercial stretches, the frontage grass gets its cut. PROFESSIONAL ALLIANCE LAWN CARE runs those mornings — mowing, trimming the sign bases and light poles, edging the walks, blowing the lot lines so nothing tracks in through a doorway. A tidy band of green at the curb is the first thing anyone sees of a building, and holding it week after week through an Illinois summer takes a route and a habit more than a heroic effort. Houses on the residential side get the same round on the same terms. By the time the workday starts, the crew is two properties on down the road.
