My schedule is wide open except July 6 - 11 so far. I would take a look at fall if you are planning on this year. By August I can have a very good idea of the late run silver salmon and how the trout & grayling fishery is looking for September.
I know we like to book way in advance.......... but last fall I canceled 2 advance booked trips because of the flooding. When you plan months in advance I keep you up to date on what's happening right up to your flight date. That's the only way to know what to expect.
I'm not trying to scare people away, quite the contrary, I'm trying to assure anyone from the lower 48 who plans a trip to get the very best results
