Out here the day arrives from the east, straight across the open plains, and it finds the grass already wet. AAA Reliable Lawns LLC starts its Firestone routes in that first cool hour, when dew still sits on the bluegrass and the mower leaves a dark band behind it that you can see from the porch. Mowing, edging and string trimming, one yard at a time, until the lines run true along every walk and fence. By noon the high-plains sun gets heavy and loud, so the hard part is finished before it starts. What's left is a clean lawn, the clippings blown off the concrete, and a yard that looks like somebody meant it.
