If you want to stop the NR rush then you need to first stop the state Iowa from handing out "Celebrity Tags" at will. This is like Sutters Mill and a guy not being able to keep his mouth shut and yelling, "I just found GOLD!"
Your "Resident" celebrity hunters have sold you down the river too. Why would expect there NOT to be a problem in Iowa when you've been pimped out and pumped up to point that people think Iowa only grows 200+ bucks.
I promise you this, again, this year, someone will have the stones to post a picture of themselves cuddled up to the Lakosky's at the IWC, (who incidentally, just purchased a fifth farm in your area that you used to hunt), all goo goo eyed and grinning, and then complain about the onslaught of NR hunters.
It's your problem and only you can fix it. It won't happen moaning about it on a IW either. You have to take it to the House and win.
"Now remember, when things look bad and it looks like you're not gonna make it, then you gotta get mean. I mean plumb, mad-dog mean. 'Cause if you lose your head and you give up then you neither live nor win. That's just the way it is." - Josey Wales
