I got a whopper pike on a double willow spinnerbait a couple years ago just south of Grassy Island over 6 or 7 foot deep with thick weed clumps while fishing with Wayne Carpenter. He got it on film. I said I just missed 'one' and also said it was probably a big pike AND threw back to the same spot anyway and BANG! I should have known better.
We both laughed. So I guess if I want to catch a big pike, I'd head to those big weed clumps south of Grassy outside of the North Channel.
