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 one pretty clearly keys to Kogotus, but it also looks fairly different from specimens I caught in the same creek about a month later in the year. With only one species of the genus known in Washington, I'm not sure about the answer to this ID.
1. Don't fish for food its cheaper to go to the grocery store than it is to buy all the gear you will need to fish.
2. If you keep fish, eat them don't let them get freezer burn!
3. Support the businesses who are willing to teach you and answer your questions, don't buy gear from someone who has "it" in stock but is not willing to give you the time of day.
I deal with this every day it drives me crazy! Hope you agree!
