The old limestone walls on Collins Street have taken a century and a half of Illinois weather and still stand square, which tells you what this climate does and does not manage to wear down. Ricardo Quiroz Landscaping works out in all of it: mowing, edging and trimming through the growing months, cleanups when the season turns, then plowing, shoveling and salting once the cold takes over. Joliet hands you humid green Julys and Januarys that arrive on a hard northwest wind, sometimes with an ice storm tucked in between. Handling both is the trade. A lawn kept even all summer and a driveway opened before breakfast in winter come out of the same habit of showing up.
