In July the brick storefronts along Broadway hold their heat well past supper, and the cicadas make a sound you feel more than hear. Green Grow Lawn works the yards behind those blocks at the cooler ends of the day, mowing at a height that keeps the Bermuda from scorching and trimming tight around porch steps and old iron fences. Clippings come off the walk, and the edge along the curb goes back to a line. On a downtown Edmond street, a freshly cut lawn in the evening smells like the whole summer at once. Homes and small properties in Edmond and just south toward the city line.
