St. Louis is actually referred to (by its tourism board, at least) as "The Gateway to The West". So, if it's not mid west, I don't know what they're thinking.
IIRC, the term was founded when "The West" was pretty much everything west of St. Louis, but it's been decades since primary school, so I could be (and often am) mistaken.
To say nothing of Idaho... What bunch of fucking morons. The state is one away from the left coast and they're calling themselves "mid" west? Are they actually that stupid? (Yes, rhetorical.)
Stroke, surgery, head trauma, misprescribed medications, undiagnosed mental/emotional health triggers, you name it. People can change, and often enough so do without their own choice in it.
So, like sand?
