Down in the Plum Creek bottom the shade falls heavy and the grass grows a different way than it does up on the open prairie. Bubba's Lawn Solutions cuts both kinds — high and lush under the trees, tight and even where the June sun hits from breakfast to dark. Mowing, weed trimming and edging make up most of a Lockhart week, with brush and overgrowth knocked back whenever a lot has gotten ahead of somebody. There is a plain pride in the last pass of the mower, when the lines run true and the yard finally sits still. Grass out here grows fast enough to keep a person honest.
