My state went to that a few ago. It really increased the age of our bucks, but I imagine a lot of spikes and forks either got left in the woods or smuggled out, mistaken for a doe or legal buck. I was against it at first, but then I saw what it did for our buck size, and I was OK with it. I am sure I've let some legal bucks walk because I could not confirm the 3rd point, but so be it.
Now I'm hearing talk of main-beam and width restrictions. I'll have to draw the line there. I feel like we gave the trophy hunters an inch, and now they're trying to take a yard. I'm in Arkansas, not Iowa. With some exceptions, we grow little bucks and we kill and eat them, and a lot of us are fine with that. Excuse the rant, but this emphasis on trophy bucks is starting to get to me.
