Orange Park Acres keeps its dirt trails and split-rail fences, and on a summer morning you can still hear hooves before you hear traffic. GREEN MONKEY LANDSCAPE takes the big lots out that way, where a lawn is an island of green in a lot of dust and pepper-tree shade. The mowing is real work here — wide passes, a true edge where turf meets the trail, a blower run that puts the dust back where it came from. Weeds come out of the bed lines before summer hardens the ground around them. There is a plain satisfaction in a horse-country yard that reads tidy without pretending to be anything but a working piece of ground.
