Midsummer noon on Butler Avenue: oleander in bloom, bicycles wobbling toward the sand, heat coming up off the asphalt in sheets. Mow Better Lawn Service is out in it — mowing, edging, string trimming, walks blown down — because a Tybee lawn in July will not wait a week. Cottages and rentals here need to look ready every Friday, and that means a route that keeps its day. When the crowds thin after Labor Day the island exhales and the work eases into cleanups and cutting back. The point of all that noise is the quiet afterward: a cut lawn, clean edges, nothing left on the path.
