I was born and raised and currently live in ND. I spent 4 years in AZ. I felt like the summers in AZ were much worse than a winter in ND. That being said I was raised here and this is what I’m used to. I felt like eirher one is miserable, but I got borderline depressed in AZ in the summer as there’s zero relief in sight, until October. In ND jn the winter, it might get down to -20 for a low for a few days but there’s always relief on the horizon. We get what they call Chinook winds and they’ll bring in some 40-50 degree days here and there throughout the winter. Sometimes weeks of it. Helena will be even warmer. You can atleast go out in it and enjoy the day. The summers I spent jn the valley, there was a 0% chance of any change in the weather, even the Monsoons just brought humidity and little relief in my opinion.
As far as the hunting, MT public land hunting is not as good as AZ, BUT, you get to hunt every year. OTC rut hunting for elk and deer every year. You can very easily kill a small 6pt bull elk, and a 150-170 class muley or 135-150 class whitetail every year if you hunt a little. You can’t do that every year jn AZ with the draw. Antelope are about every other year for resident draw. AZ otc is coming to an end so if you want to hunt elk and deer every year, MT is your place. Breaks archery elk tags are every other year or so and may not offer the top end as a high end AZ elk unit, but you’ll be hunting 300-330 bulls daily in there. The bird hunting is expceptional if that’s something your into, and the fishing top notch.
