I agree with the above statements. It's not something you just want to jump into. People are killed every year running these rivers. I'm not trying to discourage you but it can be dangerous. If you want to give it a try wait until July when the levels go down a bit. Also you may want to run the section from Rancho del Rio to State Bridge. The fishing is not as good but is more mellow. Also there are usually more people there should something go wrong. Good luck and tight lines.
