Saturday morning on the cul-de-sacs off Mount Zion Road sounds like sprinklers, screen doors and somebody's mower two houses down. Hernandez Lawn Maintenace is part of that sound most weeks, keeping Morrow lawns on a cut that never lets them go shaggy. The mowing is steady, and the string trimming is where the care shows — around swing set legs, basketball poles, the mailbox that leans a little. Drives and walks are edged and then blown, so nobody tracks grass indoors. A front yard that looks tended changes the way a whole street feels.
