While the salmon fishing will be pretty good this year, esp. about that time, for a fly fishing target, I'd vote for searun cutthroat. They will also be in around then, run 12-18 inches, are a great fly rod fish, and few people fish for them, cuz most folks are after the salmon. My e-mail address is andrewbr@attbi.com. Jot that down, and drop me a line closer to your arrival, and I'll be happy to help you try to find some fish.
