Fly fishing is a pursuit that provides endless opportunities to learn. You can learn about the subtleties of the way a fly rod moves, the lifecycle of mayflies, the feeding habits of fish, and characteristics of a body of water. Just when you think you’ve figured it all out, you discover a new layer to peel back. And so it was for me this past weekend on Penns Creek (“Penns”) when this amazing trout fishery served me a big piece of humble pie. This wasn’t the first time Penns Creek served me. I still remember my first several visits to Penns Creek during my time at Penn State. I remember hearing about how amazing the trout fishing was, how large the brown trout were, and how prolific the hatches could be. On my first three trips, I didn’t catch a fish, let alone hook up with one. Penns has a funny way of either giving you the greatest day on the water, or grounding you and reminding you that even the most experienced fly fisherman can’t tame it.
