I knew an old timer, that would do something like that. There were two deep holes that would hold fish, he would take 2 cans of cream corn. Drill holes in the top, put 4 oz of weight on the to sink (the day before opening day. He said the scent drove them crazy, and would not hit like trout do in the very beginning. He would use whole kernal soaked in cream corn juice. I will also say I saw him a few day later throwing a treble weight to remove the cans. Now I'm talking about 30 years ago, so he was the old timer to me.
