It never ceases to amaze me what I find as I float through the mangroves around the Key West area. These Mangroves act as a filter for the waters around the keys. The capture things that are floating through them. The deposit the stuff they catch and deposit them at their roots and build a base for their key growth. The treasures that you find among them is always amazing. You can find anything from old bottles to floats and everything in between. I just love to float into the natural channels and tunnels they form. ;o)
