Well, it depends on where you're exactly going. If you're heading towards the Hoh, I've had alot of luck on red flies. Usually either marabou flies or woolie bugger type flies in red or red/black. I caught a really nice native hen last year on just a plain red marabou fly with some red flashabou highlights on a sz 1 salmon fly hook. It all depends on water conditions. I'd tie up some pink, red, red/black, green/black, and purple flies. (if by chance it's gin clear a sz 4 salmon hook in black marabou may be handy too). I usually have a good assortment of all those and usually can hook into something with one of them.
