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've lived in Washington for three years and not yet caught a steelhead, or even really tried, in the famed rivers of the Olympic Peninsula. My wife and I had a brief window to get away for about a day and a half and did some exploring over there this week. However, with the short days, beach time, and rambunctious new puppy, I didn't get much serious fishing done. I fished some promising water on the Hoh for about an hour, seeing no fish but talking to others who had, and I spent all of about ten minutes swinging a fly through a run on the Sol Duc. I'd love to get back there for a few days of serious fishing when time allows.
