I wouldn't be embarrased if I were you. You had a day of fishing with your friends, the weather was nice and you weren't at work. Sounds pretty good to me. Personally I have had many days where we zeroed out on the target species. It happens. Thats why it's called fishing not catching. Hopefully you learned some new techniques and approaches to catching salmon and thats way more important than a couple of fish. You'll get 'em next time.
