Lyons follows the Des Plaines River, where the water bends past Hofmann Tower and the old portage ground stays green well into August. Lawn care here answers to that river-bottom soil — some yards hold moisture all summer, and others go crisp by the Fourth of July. DR. SPRINKLER Irrigation works both cases: mowing and edging on schedule, trimming to the fence lines, and keeping sprinkler zones set so the water lands on grass instead of on the driveway. A lawn that comes through a hot Cook County August still even and green takes attention, and that is the part worth being proud of. The streets off Ogden Avenue and the blocks toward Riverside and Brookfield are the regular ground.
