Dawn along Route 66 through Davenport is the right hour for it. Dew still sitting on the blades, no wind up yet, the light coming in low and flat across the section lines. Hane Mowing Services is out in that hour with the decks down and the passes running straight, the string trimmer working tree rings and porch steps, the blower clearing the walk before the truck rolls to the next place. The grass gets cut at a height that will stand up to an Oklahoma July, not just look sharp on Saturday afternoon. Three yards finished before most of the county has poured a second cup.
