The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.
I have been fly tying and fishing for over 30 years now. I'm grew up in SE Minnesota, and now living in Wisconsin. I know just about every rock and rapid on hundreds of miles of trout water in Houston County Minnesota. Most of the hatches and honey holes.I used to do fish taxidermy, now I build guitars.
