How much traveling do you plan on doing outside of hunting season? Being retired with nothing to do, you will be busy scouting some in the offseason, but if it were me I'd want to be within 3 hours of a major airport so I can get anywhere in the US in a day if I need to.
If you don't like winter weather, Texas could be considered, but I live here and wouldn't move here to retire. Southwest Colorado, Central or Northern New Mexico, anywhere in Wyoming I'd give a vote for. Any of those, you are a days (16 hr) drive to most any good unit in the west. Colorado is rugged in the winter with real high elevations. If I retired at 60, I'd wonder how long my knees and my back would keep me topping fourteeners before I broke down.
AK might be good if you don't have any family in the lower 48. I think the older you get the more important it gets to spend time with family and its nice to be a day away if you need to get somewhere.
