Hexagenia limbata

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.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Thanks Lloyd. I fixed it. When someone is adding as many new specimens as Bob has lately, it's easy to accidentally skip over one of the little dropdown menus and leave it set to the default, and the site doesn't have automatic safeguards against overlooking stuff like that... so the users are the safeguard.
