On our way, we had to cross some fairly intense rapids. We had a local guide with us to tell us where to take the boat. I admit, my prayer life went up a few notches. Last March we went to Prainha with a large Canadian work team. The water was several meters higher and we were able to reach Prainha in the Portador. This time of year, when the waters low, only boats small enough to navigate the tricky rapids can go far enough upstream.
