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.
This is a young of the year brook trout that I caught and released after a quick picture. I included it here since it's about of the size one might imitate with a streamer.
I apologize for the horrible quality of the picture; this was taken a year or two (and a camera or two) before I started Troutnut.com and learned how to do photography.
