I have been fishing the Cowlitz since the late 60's and I would have to say that Clancy Holt would be my choice on the river. He has been on the river longer than most of the guides put togeather. As with any guided trip, what you see and learn on the trip can always be used at a later date. If you are really wanting to learn something on the trip, be up front with the guide and tell them what it is you are looking for. I have done that up on the Fraser River with Harrison Bay Guide Service. Told them up front that I am there to see and learn some of the river.
