Sullivan keeps its life around the courthouse square, where a small theatre still lights its marquee on summer nights and the lake sits a short drive out of town. Richter Landscaping and Fence tends the lawns filling the blocks behind that square — mowing, trimming, edging, and clearing beds and walks so a yard looks intentional rather than accidental. Central Illinois summer arrives humid and then stays, and grass here grows in bursts after every storm that comes up off Lake Shelbyville. The route is planned so nobody ends up being the shaggy yard on a Friday. Cut clean all the way to the sidewalk, one lawn lifts the whole block a little.
