On a June evening the lawn at the Fred P. Hall Amphitheater fills with folding chairs and blankets, and you remember what mown grass is actually for. Peter Campobasso Landscaping Inc. tends that same idea at household scale across Palatine, mowing, edging, trimming and cleaning up yards meant to be walked on and sat in. Turf here has to survive July heat, an August dry spell and a heavy leaf drop, and steady weekly attention is what carries it through. The pleasure in the trade is the finish: a straight edge along the walk, the clippings cleared, the yard handed back better than it was found. Small things, repeated, that add up to a place people like being outside in.
