More Fun With Linguistics

Continuing with the "I'm too tired to write anything vaguely coherent" theme, here's a gee-whiz map showing what parts of the country use what generic term for soft drinks:

It's funny how there are a few islands of "soda" in the Midwestern sea of "pop." I always wondered why M. said "soda" when every other Midwesterner I've known said "pop," but now I can see that eastern Wisconsin, for whatever reason, differs from the rest of the region (save parts of Missouri and Illinois).

I wonder if there's a map showing whether people call a dollar bill a "single." Or whether someone is likely to refer to Interstate 5 as "the 5." (Is that unique to Southern California?) These are all extremely important matters, I know.
