No, I don't imagine they were. With all the water we had last year, they were scattered out all across the White, Cache, etc. Plus, with the temps never really getting cold, if they were rafted up somewhere, they didn't have to move.
I have heard that they do get thick on Lake Conway at times in the huntable area. Anchoring a layout in the center might be a way to really have some fun...
I agree we need to get Lee in on this.
