do you want to catch the browns? they are a tough catch, but they can provide a shark attack that is for sure. The rainbows fight hard and are relatively plentiful and I never bother with them. The key with the browns, or any browns, is to cover water. Any structure, 1 cast move on. Aggressive strips with as much action as possible. Pick the crappiest day available, and dont give up. There are some absolute giants in there, I never did well until I started fishing 6+ inch baitfish patterns, and it is an absolute blast when all the chironomid geeks with their bobbers watch you stroke trophies with some massive white baitfish pattern. Good times, that is about all I had for fishing for years when i lived in western washington. A lone brown trout outpost. PS, cranberry lake might have a few too.
