A few years ago I was fishing Blue Creek on the Cowlitz where the stump used to be, it was just turning daylight on about a 30 degree day, the guy standing next to me sets the hook on a fish and his feet went right out from under him while he's about thigh deep, he fell straight back and went totally underwater except for the hand holding the rod, he gets to his feet and lands the fish, he then stripped down to his shorts and hiked out.
