Morning comes to Roswell along Vickery Creek, where the water slides over the old mill dam and mist lifts out of the ravine before the day warms up. That is the hour Clean Air Lawn Care prefers to be working — blades turning while the air is still cool and the grass is still holding dew. Mowing, edging, string trimming, and a full blow-down of every walk and drive: the work is simple to name and deeply satisfying to finish. A lawn cut in early light keeps its lines all day, and the smell of it drifts down the street long after the trailer has pulled away. From the historic district out toward Alpharetta and Milton, they leave yards that look like somebody paid attention.
