To completely thrash all theories...........sorry.

About 15 years or so ago, I was using a little black and gold panther Martin for rainbows in the lower end of a tributary of one of the eastern Washington lakes that have been mentioned and caught about a 2-3 pound burbot. What was weird is the fact that it was caught in a fairly high gradient cobbly stream with some current. My guess is he was following the bait up stream. Guess I should have eaten him but I thought it was too ugly to keep.
