You guys in Iowa need to have a little perspective....
Plenty of perspective here. I lived in Michigan (Lansing) for twelve years I know where your coming from. That said I let plenty of bucks walk in Michigan also. It is true I didn't kill a Boone & Crockett buck in Michigan, but I have never done that in Iowa either. They don't come around that often. I'm not sure that most people realize how big a 170 inch (net) typical is.
In giving my answer I wasn't trying to be a smart aleck. All of the time and preparation I put in to kill a mature buck is no small amount. I
should kill a mature buck. Of course there are seasons that aren't as good as others. Over time you can't keep killing a bigger buck each year than you did the year prior. It just doesn't work that way in the real world.
Don't get me wrong, I love being out there. More than most I can guarantee that. But if I just wanted to feel the frilly feelings I get when I am in the outdoors I could save myself a lot of time, money, and effort and simply go on a picnic...
