Saturday morning in Carrollton sounds like mowers, one street after another, everybody out ahead of the heat. The GrassFather Lawn Maintenance LLC takes that ritual seriously — passes laid straight, stripes running true, the kind of lines you notice from a car window. Weekly mowing, trimming, edging, and blowing off the walks, right through the growing season. A lawn cut on a schedule holds its color and thickness in a way a rescued one never quite manages. The name carries a little humor in it; the work does not.
