Ah, your comment made me realize that my clue is not logically clear. I meant "Pop in the Midwest" as in, "It goes by pop in the Midwest", rather than "Pop in the Midwest goes by soda. As you may have guessed, I'm not a Midwest native :) so in my head I always think, "Pop in the Midwest really means soda." Thanks for your comment, I'll edit the clue!
