Small planes work in and out of the airport on Cahokia's edge all day, and one climbing out is the usual backing track to a midday mow. GreenTech Lawn Care runs residential blocks and the odd commercial strip alike — mow, trim around posts and meters, edge the concrete, blow the walks off at the end. Flat ground and a long humid summer mean the grass never really loafs between April and October, so visits stay on a rhythm rather than a whim. Fall brings the leaf work and the season's final passes before the ground goes hard. A yard held to that schedule stops looking like a chore and starts looking like a yard.
