Late in an August afternoon the wind comes down off the lake, across the old prairie and marsh ground at the south end of Cook County, and Calumet City exhales. Newson Lawn Care Solutions is out in it, mowing, edging and trimming yards from the Little Calumet bottoms up toward Torrence Avenue and the Indiana line. City soil takes a beating, so the routine matters: cut at the right height, keep the edges honest, come back before the growth gets ahead of you. When the leaves come down, the cleanup follows, and again once the ground opens in spring. Calumet City, Burnham, Lansing, Dolton and South Holland.
