June in Comstock Park is relentless — three warm days and one good rain, and every lawn on the block is an inch taller than it was. Perfection Lawn and Pest Control keeps pace on the flat, sunny lots between the river and the highway, mowing on a rhythm the grass can count on and trimming close around mailboxes, posts and playsets. The reward is that first look back down a finished yard: color even, height even, edges drawn like a pencil line along the walk. Spring brings the cleanup, when winter's litter of sticks and matted leaves comes off the turf so it can wake up, and autumn brings the long weeks of leaves. A tidy lawn is a small thing, and it changes how a whole street feels.
