September evenings in Shaw Heights stretch long and gold, the shadows of the porch trees reaching most of the way across a lawn before the light gives out. That is the hour Two Bros Mowing likes for the day's last cut — mowing, edging, trimming and carrying off the clippings while the heat finally lets go. When winter turns up, the same driveways get the other half of the job: plowing, shoveling and opening walkways so nobody has to guess where the step is. Two seasons, one neighborhood, the same eye for a line that runs straight. The plains weather here changes its mind often; the yards do not have to show it.
