Mine would be this rainbow below, the interesting thing about this fish is that it was totally unexpected. I had fished this pool ( probably 80 ft long) a number of times before and it was absolutely loaded with small browns 8-14" that were a blast to fish to on dries. My girlfriend's sister was in town and she wanted to learn to fly fish, so we went out to a private pond, I'm thinking this would be the best bet to get her into a Wyoming trout, but we got skunked.....rats! The next day I took her down to this pool that has been producing like crazy, hard not to hook into 20 or more fish in an afternoon. We get there, I rig up my girlfriend and her sister with dry/dropper rigs and nothing! I'm thinking maybe the recent cold spell has put the fish down, so I tie on a double nymph rig and begin showing the girlfriend's sister how to cast, how to mend, how to let it drift, etc and bam this huge Rainbow comes out of nowhere and hits my nymph. After landing that fish I go down to the bottom of the pool and wade across the stream and walk the far bank that is elevated off the water and all the little fish were gone, the only fish left in the pool was this big Rainbow.
