A few years ago, while preparing to gaff a clients silver, I had a pair of orca's come out of no where and steal the fish just as I was about to bonk it, scared the [Bleeeeep!] out of me.
I watched a guide buddy of mine chase a 50-60 lbs. king for about 45 min. before losing it to a sea lion. I lost 5-10 salmon a year to the *******s but never 1 that big.
