I think I need to preface this conversation which I didn't and should have. Sorry about that. My parents actually witnessed this fiasco because they were driving past and saw an empty boat floating down the river (below the scene). My sister jumped out and grabbed it and they drove the boat back to the site where they then witnessed CF's herorics. Plus this video doesn't actually show the whole scene, which is a shame. The CBS one did.
Conrad happened to be up in Banks looking for an X-mas tree. He was stopped at Banks store when he got the call. He quickly grabbed a ducky, threw on a lifejacket and helmet, and caught this tiny little eddy in front of that rock. He was facing downstream and backpaddled towards the pinned boater, yelling at her nicely to hold the stern of the ducky so he could get out and pull her off. She was stable enough and aware enough to hold the boat while he crawled back and pulled her off. Pretty sick.
