Midsummer in Avon can sit heavy by ten in the morning, the air thick, the bur oaks throwing the only honest shade on the block. J. Ramirez Lawn Maintenance works straight through it, mowing and edging and trimming close around trunks, mailboxes and the corners no machine reaches on its own. Lawns out toward Grayslake push hard in July, and keeping one even is a matter of arriving on schedule rather than after it gets away from you. There is pride in a straight line held all the way across a long front yard, and in the drive swept clean before the truck pulls off. Late in the day the grass smells like the whole season at once.
