garb72,

I have no better advice about big water than what has already been said. But, it works both ways. I call the Skagit River in NW Washington my home river. It is a big river. I think it is the 5th or 6th largest river in the lower 48. I love the Skagit and have no issues fishing it. My problems begin when I fish a small river. Especially a small trout stream. How the heck do you fish something that is only 5 to 10 feet feet wide? I have no clue where to start. How to cast. How to read the water. I am totally lost. I wouldn't even know what fly to use.
