I photographed the bar at the Green Turtle Resort for my three sons. Twenty years ago we visited Cabbage Key off the west coast of Florida. Tradition was you stapled a dollar bill to the walls, and the walls were covered. Well, the tradition holds here, too. Now they include folks donating their club birgies (pennants you fly on your boat) and these decorate the ceiling as well. Memories, connections, traditions.
In centuries past a common occupation on the coast and throughout the islands was to be a "wrecker." That meant you just waited for a ship to wreck on the reef or rocks. Then you claimed the spoils for yourself. You needed a high spot, house or tree to perch in to watch for the wrecks. There is a restaurant in New Plymouth named for this practice. Maybe this was a tree used for just such a look out.
