Co founder, John works with Petra in a kayak class.   Petra is learning how to "roll" her kayak.   This is a necessary maneuver for kayakers in order to attempt white-water rapids.   Costa Rica is home to many famous white-water rapids like Rio Pacuare, Rio Reventazon, Rio Pejibaye, Rio Savegre, and Rio Chirripo, just to name a few!
