Fished Rocky Ford president's day weekend. Having fished Rocky Ford before, I was skeptical, but the fishing was hot. Readers should try size #18-20 brassies and pheasant tail nymphs, and size 22-26 midges. I also caught a few on a BWO emerger. A guy at the blue dun flyshop in Spokane turned me on to flourocarbon leaders and tippets, and they seemed to work really well. No problmes with the knots. I caught all my fish on 4X.
