Thanks for the reality check
With the Situk to the north and the fishing as it is to the south I figured it had to be as I imagined, and read about. Guess I fell for the PR!
Here (well I mean where I used to live) the coho population consists of residents and southern populations feeding north of their natal streams between migratory seasons. So June has a lot of coho around although mostly under 5-6 pounds with an occasional 7 pounder and they are fun on a fly when the seasons permit fishing for them - I haven't lived there in oer 10 years but there were often May and June seasons before the fall fishery in the Strait of Juan De Fuca.
But this is not pertinent to Sitka, where I have never fished so your local testimonials are valuable advice. Chinook fishing sounds real good, Mugsy I think your party is in for a treat!
I know people are down on kings on the fly but if you are able to do it and pull it off big kudos.
