September light on the marsh has an edge to it, and the palmettos rattle whenever the breeze finds them. R & J Lawn Care Service LLC works the yards between Montgomery and Sandfly in that stretch, still cutting weekly while lawns further inland are calling it a year. Sandy ground, salt air and long warmth make for turf that keeps pushing, so the trimmer and edger stay busy around fences, beds and mailbox posts. The finish is the point: a clean margin, an even height, nothing left scattered on the concrete. Ordinary and exact, one week after the next.
