Even though I have only been fly fishing for less than a year, I do have that "one that got away". Not necessarily because it was too big to handle, but due to a bit of inexperience and technique, I was taught a very valuable lesson.
I am lucky enough to have a job where I alternate working mornings vs. working evenings, when I work in the evening, I don't start until 1:00, so I take the time from when I drop the kids off at day care to hit the Bow to do some fishing. One morning when I was partaking in a quite enjoyable morning, I was casting to some rising fish in a fairly still little pool tailing off a side channel. Little risers everywhere, causing the little splashes here and there. I tied on a caddis and started practising my presentations. Was quite frustrating at first, watching them rise all around my fly, but not TO my fly. Tried some different sizes, and finally (although I think it was luck more than anything as I do believe it was in a "foam bath") I had a nice little rainbow take my fly. Ended up with the one currently in my dipslay picture. Was quite proud of myself catching my first rainbow on a dry, but I wasn't done there.
After a few more casts, with no luck, I changed up again. Different colour, slightly larger, but this time when I tied on, I had a feeling that I didn't tie it just right. I gave it a "tug test" and it appeared to hold up ok, but the knot still looked a little funny. I just shrugged it off and began to strip out some line and started my false cast. On about the second attempt, I must have made the perfect cast. The line un-rolled better than it had all morning, and landed in what I deemed to be a perfect spot approaching some risers I was watching that day. All of a sudden, a large, dark shadow, came up and completely nailed my fly. It was like a ninja that thing, came from nowhere, big and dark (I can only guess it was a brown) and hit the fly hard, but with little or no splash. No more than a fraction of a second later, the bend in my rod was gone and so was that fish. I went from exhilarating high, to exasperated low in about the same speed. 0.5 seconds. When I pulled my line in, the end of the leader was all curly like the knot un-did. Ever since, I always give it a tug test and if it doesn't feel or look just right, I cut of and tie again. Fist lost, lesson learned.
I always think about that fish, and plan on going there again to get him.
