By June the ditches around Brighton are running full and the lawns drink like they mean it, and Allen Landscaping CO LLC is out early, mowing before the heat leans in. There is a pleasure in grass cut at the right height, edges run true along the concrete, the clippings gathered rather than tracked. Fall brings the cleanup — leaves off the turf, beds cut back, everything set down for the cold. Then the blade goes on, and the same driveways that were mowed at nine in July get opened at five in January. The ground here changes jobs twice a year, and so does the truck.
