Route 53 draws the line between Lisle and Naperville, though the grass on either side of it never got the memo. Green Shark Landscaping of Naperville works both sides, mowing, edging, trimming and running yard cleanups through the warm months, then plowing, shoveling and spreading ice control once the salt trucks start moving. Storms come in fast off the open ground west of town and leave the heavy, wet kind of snow that has to be pushed before it sets up. Summer asks the opposite temperament: patience, a steady week, a sharp blade. The through-line is a property that looks looked-after in January and in July alike.
