If you have taken a glance at any of the photos in the galleries of the other caches on the island, you will already know what a little piece of paradise this spot is. When I placed the cache, the river was relatively quiet, but the sound of a motorboat engine coming to a stop caught my ear. It turned out that a couple had stopped at the island and by the time I arrived, they were well settled into reading their book and newspaper while sitting in lawnchairs. They had great plan for the day!
You are looking for a camoed larger than regular sized bison tube, suspended high enough that it shouldn't be swept away in any future floods!
