West of Hensley the Sangamon slips through cottonwood bottoms on its way past Mahomet, and the air along it stays cool a while longer than the open fields do. Sims Services LLC mows and trims Hensley yards through the long green stretch between the last frost and the first, edging drives and clearing the cuttings off concrete. Grass that gets cut on time and at the right height crowds out most of its own trouble, so the schedule quietly does a good deal of the work. A yard finished in the early evening, beds edged and walks swept, is a small and complete thing. Come back a week later and it has held.
