i would be lying if i said it never happens to me...but just the other day a guy did a somersault in the current while trying to walk out to the rockpile...(no camera) i just love the look on their faces when they get up to see if anyone saw what just happened...my recent fall wasnt that bad...i changed to my studded waders and had super grip on everything i stepped on so it gave me a great sense of security and confidence that I didnt have to look down to see where i was walking (water was dirty) well i tripped over the largest bolder in the river and went forward... both arms up to my pits got soaked...and of course EVERYONE was standing watching...
