Another article from Neil that I can really relate to. I just fished the Pseudocleon Anoka hatch on the Mad here in Ohio, and they were 24s for sure. It's a very tough hatch to deal with, even if you've got rising fish. A very tiny wet fly worked the best for me, I had no luck with the smallest duns I had, even though I saw fish take one from time to time. Lots of fun!
