Over 300 people have died in Yellowstone park. One of those deaths happened on the Yellowstone River, the same day I happened to be fishing it. A flyfisherman in his 60's, apparently lost his footing in the deeper heavy current, and was dragged under by his waders that filled with water. He floated almost 5 miles downstream before he was found. I was wondering what all the emergency vehicle sirens were going.
Ironically, I came close to the same fate 20 years prior, by trying to wade across the river at Buffalo crossing. Water was as high as the top of my chest waders, as I started bobbing downstream. Desperately trying to dig the toes of my wading boots into the stream bed. I made it across, and caught Cutthroat trout by the dozens. My return trip across the river was aided by a big dead tree branch that I used as a wading staff. It scared the crap out of me.
