If you were wondering, there is a 100% chance that the people in the boat got soaked to the skin, and a very good chance they were glad of it because:
1) The weather was pretty hot, and
2) Many of them needed to wash their underwear!
We did see several creatures along the way...
These last guys with the raccoon-like tails are known as "coatis" or "quatis," and they have been known to pick pockets, snatch anything shiny from tourists, and be quite aggressive around food. Cute as they may be, they can do a lot of damage to dogs or people. I captured them in their natural habitat, the trash receptacles!
Not much I can add to what you have seen, except a couple of small videos to attempt to capture the power and sound. Enjoy!
