So, I was fishing on the St. Joe on Sunday afternoon. There was no hatch going on that I could see, but a number of fish were rising regularly. The hopper I'd been fishing wasn't getting any love, so I tied on something called the St. Joe Special that I bought in St. Maries. As I was tying it on, the improved clinch knot got wrapped around itself a little, and looked slightly off when I tightened it. But it seemed solid, and didn't appear to slip at all when I pulled on it, so I figured it was ok. I'm sure you all know what's coming next. On about the third cast, the biggest trout I've seen so far (I've only been fishing a year, so it's probably not that impressive) came up and inhaled it. I only really saw its mouth (it was facing straight-on at me), and it looked like I could have put my hand in it. It's mouth was big enough that my first reaction was that it was a bass, but I don't think there are bass in that part of the river. Anyhow, the inevitable happened. The fish took off downstream, utterly unfazed by the drag. After about 2 seconds, everything went slack. When I reeled in, my knot had unraveled and the fly was gone. Aaaaarrrrrrggghh. Well, now I know. If you're not absolutely sure the knot is right, retie it. The extra 15 seconds it would have taken aren't worth the mental anguish of losing that fish.
