July in Tittabawassee Township is heat shimmer standing over the soybeans and cicadas going all afternoon without a break. GLS Lawn Service LLC mows straight through it, along with trimming, edging and the cleanups that bracket the season on either end. There is a rhythm to a summer route — the same yards in the same order, the grass telling you how the week's rain actually went. Cut a little high through the dry stretches and a lawn holds its color while the block around it goes tan. That is not luck, and it is the part of the work worth being proud of.
