Not really. The southern midwest and northern midwest are pretty distinct, and the bootheel of Missouri has more in common with Oklahoma than with Iowa.

Lots of Missourians don't make it north of of the Mason-Dixon very often. I'd definitely expect more KC folks to make it to Colorado than to Minnesota. Etc.

Not sure why you'd prime facie expect Missourians to have a better mental model of the upper midwest than Californians. If you don't go to a place, you don't go to a place. Doesn't matter if it's around the world or six hours north.
