I hear ya cajunman - when I was growing up in the south everything carbonated & non-alcoholic was called a coke. Now everyone in CA calls it soda. I still hear frineds from the midwest call it pop.
We first had coca cola light in Spain. Last year we visited the Coke headquarters in Atlanta, GA. Man, they make a lotta stuff for a lotta different places and coke goes by a lotta different names. Thankfully one of the most important things I've learned from this Board is - no matter where you are - ask for a Belikin!
