Saturday morning in the Woodglen cul-de-sacs sounds like garage doors, sprinkler heads ticking, and somebody's radio two houses down. Clean Edge Lawn Care LLC fits right into that soundtrack, moving through the loop with mowing, trimming and the edging the name promises. Cul-de-sac yards are all curves — pie-shaped lots, arced walkways, a mailbox pillar and three fence posts that a mower will never reach — so the trimmer does the honest labor. The lawn ends up with borders you could draw with a straightedge, and the driveway gets blown off before anybody comes out to wash a car. It's a small, complete kind of order, delivered before lunch.
