Comparing Iowa's deer herd to Arizona's is truly apples to oranges. We have some monster muleys and the Coue's whitetail are a blast, but an adult Coue's whitetails is still smaller than a yearling Iowa whitetail. Most Iowa does are bigger than most AZ bucks of either species. Having said that, I'd buy land in Iowa in a heartbeat, but not strictly for hunting purposes. I grew up there, spending the first 23 years of my life there. Iowa truly is one of the best, if not THE best, place to raise a family. At some point, I'd like to move my family back there if I can tear myself away from the mountains and big elk. I'd consider spending my summer/fall in Iowa and then coming back down to Arizona in the winter (especially after seeing your winter this year)! Of course, I wouldn't leave for Arizona until after the rut!
I hunted a family farm in Iowa back in 2011 and harvested a nice buck. I've actually said the following before in a post a few years ago asking the same question. I'd buy land there, but I wouldn't expect or demand that I get a tag to hunt deer every year. I'd play the waiting game just like any other NR. That's the way it should be. I don't think NRLOs in Arizona (not that we have a bunch with all of our public) should have a tag to hunt every year just because they own land. Every state should always favor its residents over its NRs. If (when) I own land back there, I will have it managed by a trusted resident friend or two who will have sole access and hunting rights every year that I don't have a tag. My wife and I have spoken several times about buying out part of one of the family farms I hunt when my cousin's parents pass away to ensure that it stays in his family. His siblings have no interest in it, so we figure we'd buy those shares and then sell them back to my cousin's youngest son when he's got his feet under him. That way, the family farm will always stay in the family.
I may have a different approach and motivator than some NRLOs, but that's where I stand.
