I love dipping the Copper River even though it's pretty dangerous (relatively speaking). I have always wondered if it was possible to put an anchor of some sorts into the rocks to tie yourself off on. Just like the rock climbers do when they climb. I was thinking of putting a few in that stay there permanently so everyone could use it. I know nothing of how these work or even what type of rock we fish from (north bank). Any ideas or inputs as to the good/bad of this? I'm not doing it for sure, but I have been thinking of it.
