On the west edge of Forest Park the Des Plaines River loops through old oaks, and the grass out that way holds dew until well after the commuter trains have gone. McAdam Landscape Professionals mows into those long shaded mornings, cutting at a height the trees will forgive, trimming clean around trunk and post, edging drives and walks so the boundaries read sharp. Shade lawns near the river are their own puzzle: thin in places, thick in others, always damp. Solving that puzzle week after week is what turns a patchy yard into a green one. A finished cut on a June morning here, with the light coming sideways through the oaks, is a genuinely satisfying thing to stand and look at.
