Welcome to reality :) I think the lakes out your way were in many ways the last frontier of untapped swimbait fishing. From what I gather, there was some stupid good fishing last season. Now comes the hangover. Fish just get smart, it's the way it goes. I've been lucky to be on the front side of great bites before and I've seen what happens afterward. It just means you have to think up new ways to catch them. There will still be fantasic days on most lakes even after they've been hit hard, but there's usually only one year of really good stupid easy swimbait fishing on any given lake in it's lifetime.
