I did a little experiment this evening (because why the hell not). I wanted to see which states Idaho is most commonly grouped with when the country is split into “regions” (because I’ve seen it put into the Pacific Northwest, the West, the North West, etc., each with different states along with it). So I went to Google Images and typed “regions of the US” to see what I could find.
I looked at 50 different maps and recorded how many times each state (apart from Idaho, of course) was grouped along with Idaho.
States like Mississippi and Louisiana and such were grouped on some map showing the nuclear regions (or something like that) of the US.

Interesting to see the difference in grouping frequency between our state to the east (Montana) versus the two to our west (Washington and Oregon)
