Couple or three years ago, a buddy of mine and me were camping overnite on one of our favorite Jacks Fork holes. Sitting around the fire just before dark, had a female otter cruise by us raising a little cane. Seconds later her man came up, got on the gravel bar, and tried to charge us! We jumped up and started yelling at him and clapping our hands and he went back in the river and followed her. Heard them come back downstream around 2:00 A.M. Had caught fish from the hole before this took place. Next morning... not a bite. And to think I actually rescued one from a trap years ago from Coal Camp Creek!
