I think if passed it will erode more of our hunting heritage. We will become more like TX. Put out a feeder and sit and wait. And please don't start with the food plot is the same thing. This is simply my opinion.
My opinion is somewhere in this ballpark.
1) I enjoy the deer hunting traditions we have now, and when it transitions to Texas-style I will enjoy it less. Yes, I know I don't have to sit over a feeder.
2) I also think baiting will increase the progression to an "arms race" of everyone frantically corning more than they perceive their neighbors to be. Which makes hunting that much more expensive than it currently is.
3) Bating is bound to increase conflicts within club environments as well ("I can't believe you went in sat in that area and killed a buck ... you haven't filled that feeder up all season blah blah blah").
4) I can see where supplemental feeding of any sort (regardless of whether someone is within 100 yards with a rifle and an intent to kill) could help spread disease. A 10 ft diameter feeding circle is a much higher concentration than a 1/2 acre green field.
I don't really have any ethical concerns. As many have pointed out it's essentially the same as sitting on a field, which I already do some.
Like Elkhunter said, all this is just an opinion. Just like those who have emphatically argued for legalized baiting while that bill was up for vote.
