This was an amazing exerience...the curves on the water are the wake from our boat...the people in the other boat were from New York City..an Opthamologist and his wife who had attended a conference in Sao Paulo and were doing this as a side tour...what you don't see is that 20 minutes later we were in a windy and rainy thunderstorm.
It was a magic place that I would return to in a minute...nice to say that about places and people you experience isn't it!
