The bow of the boat is pinned against the shore, and that is where we have rope attatched to it, but even if the boat comes loose I don't think it will be a hazard. It will just swing up against the right bank. Like I said I would be really suprised if a boater saw it on their way down without knowing exactly where it is, you could boof right over it and not see it. It is located right next to the highway, directly below a forest service access or information sign with an arrow pointed to the right. It's pretty much at the end of the steeper rapids where it starts to mellow out. I'm not going to out a swimmer on the buzz, but if the boat does come loose let me know and I can call him.
