There are a few of us working on the problem. My experience has been the same as to those few and far between times when the gods smile and kings are on the bite - where we can target them. We were in Sitka a few years ago and there was a big batch of kings working candlefish off Biorka. We hooked three the first day and lost all. That night it started to rain and didn't quit for 7 days. Not a little rain, buckets! Bait went down and couldn't locate kings again. End of story.
Did catch a 30 and a 35 a couple of years earlier in Olga Strait near Sitka. Evening with a mix of coho and kings working a point. First year we really were up there so thought that although it wasn't necessarly common, it did happen. Little did we know.
Neah Bay research mission sounds great. Have my 19 foot Whaler on station all of August but work will get in the way much of that time. Should be out most weekends into September. Let me know if you are coming out. W
