We’ve seen this map before, but the comments are interesting: e.g. the anomalous “soda” around the University of Iowa, in the midst of “pop” country, the east-west divide in New York, the “soda” enclave around St. Louis, the weird coloring of northern Alaska (probably too few data points).

Note from KBJ: The correct term is “pop,” and frankly, it pisses me off that anyone would call it anything else.
