Sunday morning along Miramar and Topsail beach east of Destin, FL. Yet more fatbiking, but this time in low-60F, sand, breeze, calm. Ventured into Topsail S.P. to find muddy trails and bogs to ride through, along with dunes to explore. Highlights include beach riding for first time, mud-bogging on fatbiking, what's around the next corner, almost waist deep hoping too cold for alligators.
