I have a friend that used to work for a charter business that I fish with every once in a while. Last summer during the humpy run he bleed this pink out with one of his tricks. I didnt see exactley how it was done, because he did it so fast, but that fish was shooting squirts of blood at least four or five feet out. Pretty neat to watch. After he did it he looked up and just gave me a smile. Tomorrow were going out in the sound/morning, then on the snoho in evening. If he does it again, I will pass on the knowledge.
