A good haircut and a good lawn share a secret: it is the edges people notice. The lawn barberz Inc. works Sandersville yards on that principle — an even cut across the top, a tight line along the drive, the neckline where grass meets sidewalk trimmed close and swept clear. Mid-summer here is a standing weekly appointment, because under all that sweetgum shade and Georgia rain the grass grows back fast enough to keep anybody honest. The trimmer goes where a mower cannot, around the posts and the AC pad and the base of the mailbox. Then the walk is cleaned off, the truck door shuts, and the yard looks like somebody paid attention.
