The boat eases out of Goodland Boat Park as tide pulls the Gulf across a chain of mangrove teeth. Salt spray beads on the shaded canopy above the deck while a captain with a soft Gulf drawl points the bow toward a scatter of islands—Neal Key, Ramsey Key, Little Tide Key—each one a low, wind-bleached ring of sand and mangrove roots. This is the Ten Thousand Islands, a place where the shoreline refuses to stay fixed and the surf keeps depositing curiosities: olive shells, cone fragments, and the occasional luminous piece worthy of a collector’s eye.
