@blueberry1222 In one of 2 rafts going down grade 4 river. Boat my partner and I were in overturned and a few of us were caught underneath. Managed to get out. I drifted off but was picked up by other boat. Others managed to get boat turned and climbed back in, but one person missing. Eventually spotted him face down in water. They raced to him, dragged him onboard and applied CPR. Fortunately he came round and rescue helicopter sent for. By chance we bumped into him a week later. He had no memory of the event.
