First off let me point out to you that I said Might and underlined it because I did not know about Illinois and Iowa, other than the fact that they kill big bucks there like they do in Texas and KY. I have said on here many times that my experience with shooting over bait in KY, over the past 11 year 3 or more trips a year, has shown me that the big bucks do not come to the feeders during the day time(usually). In those 11 years we have killed many large bucks and I don't recall a single one being killed at a feeder.
That being said, if baiting is legalized if one does not wish to one does not have to use it. I doubt that baiting on private property will pull many bucks off the unbaited public property.
