Sounds like a great day. I haven't fished for Kokanee before but if I had a boat, I'd be all over it. What I have heard but correct me if I'm wrong, is that it's the sugar that the fish are attracted to so I'm guessing that's where the corn comes in. Recently, on Outdoor GPS of one pro-kokanee fisherman said that he's used syrup before (I think it was maple but maybe it was corn syrup).
