Coke Vs. Pop Vs. Soda

What do different parts of the country call soft drinks? This map will show you.

So, the south says Coke, and the north says Pop. We knew that. But
look at all the Soda in the NW, and the odd patch around STL that is
that way. And East Wisconsin is equally strange, especially with it
stopping dead as soon as it hits Michigan. And there's a Coke patch
around Indianapolis. And look how random NC is! I find this really
interesting.
