I've slipped and fallen a few times. Once on damp, flat rock, out of the water. I was taking a step, and my other foot just shot out from under me. Broken a couple rod guides on a spinning rig when I did it, too.

The most embarrassing was last year. Wading out to my spot, but I had to cross a couple rock bars. They weren't that high, but the swift current sets the rocks at an odd angle. I managed to loose my footing when I hit the bar, got spun around, and went over backwards. My waders floated like a cork, as did my backpack. My rear end managed to sink the 9 INCHES to the bottom. I stood up, and looked around to see if anyone was watching. Luckily, no one was.

I now take a different spot to my usual fishing spot. Only one small rock bar to cross, and that's almost gravel-sized rocks.
