In the evening the planes come down over the southside toward Hartsfield-Jackson, one behind another, low and lit against a sky going pink over Morrow. JR Lawn Maintenance is usually finishing about then — the last yard cut, the trimmer cooling on the trailer. Warm-season grass here asks for mowing you can set a calendar by, and the work pays back the repetition. String trimming squares the corners a mower rounds off, and a hard edge along walk and drive keeps everything from creeping. Cuttings are blown off the pavement, and the yard settles into the dark looking exactly as it should.
