I might be old---but I'm good.
Well,since I don't really target them I don't know to much about them up there. I've seen them up that high in the summer. In fact I caught one,a fin clipped buck about 21" long. In the west fork of the Foss river. I was using my 7'6" 4wt at the time and I was just fishing for what ever.
I'm not saying that they are not there because I've seen them in the Beckler and the Tye rivers. Had one on in the Beckler,but it didn't last long. But was fun while it was on.
One other note. This was in the month of August when the flows were down.
