Berwyn's avenues carry the names of trees and towns, and between every pair of houses runs a gangway just wide enough for a mower and a person to think in. Miguel's Lawn Service moves through them all June long, cutting, edging, trimming close to the foundations, hauling the clippings and keeping the beds clear. On lots this narrow the difference between an average lawn and a fine one is a couple of inches at the border, and that is where the care goes. Nothing about it is grand; it is a green rectangle kept honest week after week. Multiply that by a block and you have the look of the whole town.
