I caught a fish on a damsel dry fly pattern at Rocky Ford in June of 1992. I was 22 years old. It was awesome.
I too have had fun with adult damsels at RF. In that I live about 20 minutes from the crick, perhaps I should go try it this week....This is hilarious...in it's own right, but also because one of the best 30 minutes of trout fishing I've ever had was at Rocky Ford in June of 91 fishing dry damsels. Me & my buddy had multiple doubles in that 30 minutes. We still laugh about that one. We had just spent a week in Montana and the best fishing of the trip was our brief stop at Rocky Ford on the way home.
This was followed by about 3 minutes of terror running back to the truck hoping to avoid death from a lightning strike. I was 23 so tempted the storm quite a bit longer than I would now.
Hope you get to catch another fish on a damsel dry. Haha!
