Come September the oaks along the forest preserve on the southeast side of Niles begin dropping in earnest, and every yard within a few blocks inherits the fallout. M Randazzo Landscaping Inc stays ahead of it — mowing while the grass still runs, trimming and edging each week, then blowing, raking and hauling leaves as autumn fully commits. Fall light here comes in low and long and makes a freshly cut lawn look lit from underneath. There is genuine pride in walking off a property that has nothing left on it but grass. Then it is on to the next one, before the wind changes direction.
