27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

I really hoped to catch some good blue quill specimens on this trip, but they are very fragile mayflies and this one was in the best condition of the few that I caught after I drove them home to my camera. It may not be pretty, but you get an idea of the size/shape/color anyway.
