Fishing a north Puget sound river last July. Wasn't really a fishing trip, just camping with my wife and some friends. Thought there might be some dollies around so I grabbed my ultralight trout rod and tied on a small black roostertail. I made a cast into a pocket where a small creek joined the river. A few cranks on the reel, and my rod doubles over. Up to the surface, shaking it's head was a 20# or so summer chinook. That fish took off like no tommorrow, and fought like crazy on such light gear. About 45 minutes later, I landed and released it. I couldn't believe that the 6lb. test I spooled on for shad fishing held.
