Grayson's newer streets tend to end in cul-de-sacs, so a lot of front yards curve — and a curve is where you learn whether someone edged the lawn or only ran a mower past it. The Lawnmower Boys take those curves seriously: mowing, string trimming, edging along walks and beds, then a full blow-down so the driveway looks as tended as the grass. Late-summer evenings are the good hours here, heat easing back, a sprinkler ticking somewhere down the street. A yard cut that morning still shows it at dusk, and that is the measure worth working toward. The rounds cover Grayson, Loganville, Dacula, and Snellville.
