Not the poster, but one practical reason - bugs can really cut into the outdoor enjoyment, and in colder climates ‘bug season’ is generally relatively short (but intense). Usually spring and early summer.

Warmer humid climates, it’s common to only get (at most) a few months of ‘no bugs’.

Chiggers, ticks, noseeums, mosquitos, black flies, etc.

Also, warmer humid environment mosquitos are usually tiny, sneaky, and disease carrying.

Cold area mosquitos tend to be huge, obnoxious, and less disease carrying. Easier to kill, but will bite through thick sweatshirts, type thing. (Yes really!)

Or go southwest US and only have the occasional horsefly to worry about.

Politics and culture play an outsized part. If I could easily move to Canada I would. Barring that, I'm more inclined to stick to blue states than red states. Montana is a bit of an outlier in my list. Cannabis legality is a factor (Wisconsin is the oddball here), but increasingly less so as I expect that problem to go away within a few years nationwide (and certainly in Wisconsin). Climate is a big factor. I grew up in NJ, and while I've lived in tropical places and tend to spend my summer traveling to a lot of hot places, I don't want to live in a hot, humid southern state. There are parts of NC and TN that are more more mountainous and less oppressive, but it's still pretty sticky there.

I still plan to spend much of the year traveling in an RV even after I settle somewhere. I'd be happy to spend the winter holed up in a cabin with a wood stove though.
