Stumbled on a weird and wonderful blog today that puts up strange maps and then comments on them in detail... everything from a Russian thinker's future US map (for after our financial collapse) to a map like the one above... detailing by color where people prefer to call soft drinks "soda" or "pop" or "coke." Click on the map for a closer look, it's well worth it.
Obviously the correct term is soda. But I grew up in California, so maybe that's just my cultural bias showing. Feel free to leave a comment defending your own preference.
