What Does Wyoming Prefer: Soda or Pop? [POLL]

When speaking about soft drinks, what is the preferred terminology for Wyoming residents? Is it "Soda" or is "Pop"? This debate has gone on as much, or even more, than which way is the correct way for the toilet paper roll to face (I say facing out, but that's a discussion for another time).

Could this be a regional thing? Or is it based on what the people around us say? With the Cowboy State having some many transplants, this debate seems to be split down the middle. So let's put an end to this once and for all!

*I personally say "pop", but 2 out of the 7 soft drinks pictured actually said "soda" on the container.*
