The old Seaboard rail bed still runs straight through Hiram, though it carries walkers and bicycles now, and on summer mornings a low mist lies along the Silver Comet Trail until the sun lifts it clear of the pines. That early hour, before the heat has any weight to it, is when 3 brothers Lawncare & Services gets the ramps down and the mowers rolling across grass still cool enough to cut clean. The list is short and the standard is plain: mowing, string trimming, edging along walks and drives, hedge work, and blowing every clipping off the concrete before the trailer gate closes. By mid-morning a yard that looked shaggy at daylight reads like it was drawn with a straightedge. Across Hiram, Dallas and Powder Springs that is the whole ambition — leave a place looking looked-after, then get down the road ahead of the Georgia afternoon.
