    Started listening to it last night. 1/2 way in. Really good stuff! tj

    I haven’t been fly fishing for long, but because of podcasts like this, I am learning a lot about natural history, and human involvement in shaping our fisheries. Just finished reading Halverson’s ‘An Entirely Synthetic Fish’ and this was a great follow up. Keep up the good work and interesting guests. Thanks!!

    Great podcast, best one so far. Thanks for posting sources too. Would love a similar interview with an eastcoast brook trout expert talking about range and sub-speciation.

    I agree, best of the best! So informative, particularly for those of us with an interest in Colorado’s natives. Please let Mark and his colleagues know that their efforts in Timberline, etc., were not a total loss. First, mistakes happen. We learn and move on.

    Personally, I took my daughter up there last summer hunting “Greenbacks” (only vaguely aware that they weren’t the “real” Greenbacks — now I know a lot more!). She got hooked on Tenkara after seeing the beautiful fish up there, watching them behave, and helping me land them. She grabbed the rod and between us we caught and released many, many fish on an Amano Sakasa Kebari. It was such a memorable day for both of us, and she’s now a Tenkara chic…a dad’s dream come true!
