The last day of our cruise, we'd just come back from a jungle walk. I had just showered and was wearing nothing but a little robe and Robyn had just hopped in the shower when we heard our guide yelling in the hallway 'Meeting of the Rivers! Come on deck now!' I popped my head out the door and said 'But we're naked!' He replied, 'Come anyway!', so we threw on whatever clothes were handy and rushed up on deck. The Meeting of the Rivers is the confluence of the black water Rio Negro and the lighter colored Amazon River. The two rivers run side by side for several miles, half black, half white, for several miles before the two colors blend together. It's nature's version of a black and tan. So cool.
