Doubtful. One, the fisherman that would like to see a regulation change on river smallmouth is a drop in the bucket of license sales. Besides, are you really going to not buy a license and just quit to prove a point? Do you think they will care? Really? Really? Yeah, me neither.
But honestly I don't have a problem with smallmouth fishing right now. It's a blast. Would I like to see some better fish? Yep. But I'm not going to turn something that I love doing into a big ball of stress for me. (Look at how many time Smalliebigs has quit because he was so frustrated) Besides, I've grown past the point that I need a big fish to prove it was a successful trip. If I go it's considered a successful trip to me.
Plus if I have to get involved in politics to make things better then you can just count me out. Take a look around. Politics isn't making anything better.
