Pop, Soda, or Coke?
This is interesting. I grew up in Kansas City, and we referred to any non-alcoholic carbonated beverage as "Coke". As in:
"I'll take a Coke."
Their map shows Kansas city to be firmly in the "Pop" camp, but Linn County, KS, where my dad grew up, is one little red dot (Coke) in the midst of blue (pop).
In Columbia, though, if you ask for a Coke, you get a Coke, and I just can't bring myself to say "pop". I don't know why. So I've converted to "soda", and I'm coping fairly well with the change. Obviously, some days are harder than others, but I'm doing okay.
