Dialect maps are fun. They're particularly interesting for American English, which has lots overlapping changes. The soda/pop/coke split is sharper than I would have imagined:
It's interesting to me that eastern Wisconsin and the St Louis area would be islands of soda in a sea of pop.

The St. Lois area and Wisconsin are heavily settled by German Lutherans.
