You could also give Ian Rutter (RandRFlyfishing.com) a call. He and his wife Charity (she guides, too) live in Townsend and have written a few top-notch guide books and made some excellent videos. Very supportive of the park and all-around great folks. If you do talk to him, tell him "Shark Week"'s dad said "Hi".
Fly fishing - it's cheaper than a bass boat!
