Specifically the very small ones (Wyoming/Montana/Idaho). I’ve never met anyone from any of these places. By “what are people like” I mean general personality-wise — like Southerners are typically very friendly and slow-paced, Northeasterners are typically very fast-paced and less outgoing.
Edit: the reason I’m interested is just because I never hear about these places but growing up my dad and all the male members of my family were Western-obsessed and my dad would always threaten to move us to Montana. I’m kinda curious how different my life could have been if it actually happened.
