Looks to me like at least 1/3 of the state says soda. I grew up in Kenosha Co., now live in Dane, and it's soda, grandma, pen, aunt, and duck, duck, goose for me. Always has been. And there is no such thing as a bubbler, as far as I know. They don't exist anymore. Nowdays we have drinking fountains. It really doesn't matter to me what some map tells me people use either. A Pepsi is a type of soda, and I'll never understand why people use "pop." People can say whatever they want, but that doesn't make it correct. All soda surely isn't Coke, like they say in the south; Coke is a brand of soda.
