Cut grass in June has a smell that can stop a person on the sidewalk, and Lincoln Park in June is full of it. Green Clean Lawn Services chases exactly that — mowing at the right height, trimming around fence posts and mailboxes, edging the walk until the line between green and concrete is a single clean stroke. Cleanup counts as much as the cut; a driveway blown off and swept is how a yard says somebody was actually here. Compact city lots reward that kind of attention, because there is nowhere for sloppiness to hide. The result is a lawn that looks combed.
