First light on St. Simons arrives with a racket — jays and wrens loud in the oaks, the tide turning under the causeway, marsh grass silver until the sun clears it. Jaybird Coastal Solutions LLC is usually rolling by then, with mowing, edging, trimming and yard cleanup lined up before the heat turns serious. Island lawns take salt wind, sand and long humid summers, and they repay anybody who shows up on schedule. Finishing while the morning is still cool, everything blown clean, sets the tone for the whole day. St. Simons and the neighboring Golden Isles get that early start.
