By four o'clock a Norcross July feels closer to the tropics than the Piedmont, air thick enough to lean on, thunderheads stacking up west of Holcomb Bridge Road. Royal Caribbean Landscaping works ahead of that clock, cutting and edging through the morning so the trailer is loaded before the sky opens. Heat like this pushes Bermuda hard and pushes weeds harder, so the routine holds: weekly mow, trimmed borders, beds free of weeds, drives blown down. When the rain passes the yards come up impossibly green for an hour, striped and sharp under a washed sky. That hour is the reason for all the early starts.
