Personally, I think 1 buck rule would be great. No party hunting - I don't think too many would shed a tear on that either. Both of which, I know many folks who shoot more than 1 buck & party hunt just because they can. (Kind of like some bad government hand-out they may not agree with, BUT- might as well take advantage while everyone else does).
Side note... As discussed, with dozens of experiences shared here in the past by many.... If it says XYZ shed bucks killed, many know - from experience & witness - that # is far higher. Like the many groups that have been "open" about sharing how they never call in their shed bucks as shed bucks- they call them in as does because "they want the season to stay".
Or several from the DNR stating that this season is the "worst at calling in deer".... Lots of guys, in several of their opinions, who are 1 time a year deer hunters that don't care, take time or give a hoot to call in deer. (suppose this would stem from experience on ticketing non-called in deer?).
I will say, many landowners could shoot 3 bucks. Many regular residents could shoot 2 or maybe even 25 bucks if you get enough buddies for gun season.... I can't think of one landonwer of all that I know that has either EVER filled all 3 of doing with any CONSISTENCY. Non-scientific & just my experience BUT I'd guess most landowners I know might average ONE buck a year if I had to lay $ on it. I know MANY landowners who eat all 3 tags in some occasions. No rule or solid backing here, just what I see year after year. This does NOT put landowners above others BUT... seems like most landowners I know are "giving" people.... they often think deeply about how to make an area better for others, enjoy others shooting deer, they are in to habitat, they think BIOLOGY when they pull the trigger, etc. Giving folks. Honestly, folks shooting multple bucks a year... If I ever see it, it's usually poachers (illegal obviously!!) or guys who shoot whatever runs past them (legal and not equating to poachers!!!).
But ya, beyond the long rant, I'd be cool with 1 buck. Or to go back to the permanent season Iowa has had for a long time now, Oct 1 - Jan 10.
