Indeed there is Dave. It's important to learn and try to take something positive from every trip. Even if you catch no fish at the end of the day you should be able to say to your self something like, Dam I was casting nicely today. One more thing, Putah is not a good place to learn to flyfish in my opinion, Simply because it is somewhat unique and the things that work there for me do not work any were else, putah is it's own game.
