I live here in Zone 5, and I can honestly say that I haven't met anyone local who targets bass in the winter and not many locals do in the summer either. I'm the rare exception. I love fishing for smallies in the summer. The small amount of bass fishing I have witnessed, is mainly from tourist and lodge boats . IMHO, with the small amount of people who target bass on our area lakes, I doubt that these changes would have that big of impact.
