Mornings on the oak-lined boulevards of On Top of the World belong to the walkers and the first mowers of the day. Barkley Lawn Care & Tree Service falls in with that early rhythm — cutting even, edging the walks that thread between the homes, trimming close wherever the mower leaves off. Marion County grass runs hard from April into October and idles through the cool months, and the visits follow that curve without argument. Clippings get blown off the drives so nothing travels indoors on anybody's shoes. It is the sort of upkeep that lets a whole street look composed without a single resident having to think about it.
