Some August days around Hill the air hardly moves and the shade of a pin oak becomes the most valuable real estate on the block. H.R.R Lawn Care L.L.C works through it, cutting the sunny turf and the shaded turf at heights that suit each, then taking the trimmer around the trunks so nothing gets scarred. The heat is honest about who is doing the work, and so is the result: a lawn that holds an even line from the street to the back fence. When the temperature finally breaks in October the same yards need leaves moved instead of grass cut. Hill and the roads running out from it are where the truck goes.
