pbunbury- Not sure that anyone is claiming to be an expert. However this site is populated by a lot of folks like Preston who have a significant amount of experience (old farts?) and try to stay current with emerging science and information. Those same folks attempt to share on what little they may know or have learned with others here. You can certainly ignore them if you wish but experience has taught most of us to do so will be at our loss. BTW - The WDFW char article that you provided the link to referred to the recent discovery of bull trout going to the salt and recent regulation changes. Both of those events occurred in the early 1990s. In the 20 years since that time through tagging (both floy and radio) efforts, genetic studies, and other life history work much has been learn about the region's native char in the last 20 years; it is some of the information that Preston was attempting to pass along.
