That's funny! I saw the title and thought to myself: any further north of me and it's "pop", and to the south is "coke". I say pop... And it's almost always a Dr. Pepper.
It's pop here too. Unless you're a die hard drinker of a specific brand . Pepsi , Coke Or MT. Dew Dr. Pepper now and then . Myself I'm partial to Grape Nehi go figure. I always was the weird one.
Y'all take a close look at the NW angle of MN - that green spot. While the rest of MN is pretty much solid blue/dark blue - the NW angle (Lake of the Woods and surrounding area) has got to be differant - and it beats me as to what they call it or why....
