Kayaking the Espolon River in Futaleufu, Chile with a sinking double kayak. It had a hole in it, so we had to empty it out after each rapid! Eventually it caused us to “submarine” into rocks in the middle of the river. Long story short, Mike and I were each on top of a rock with the kayak sandwiched in between. Successful rescue, lots of adrenaline, and all was well.
