Soda, Pop, Coke...or???

If your from California, when you order a soft drink you said: Soda. When I went to visit my dad and his Minnesota native girlfriend she insisted it was Pop. On a family road trip driving through the South I even heard it called cola! The map below shows where people from different regions lay their soft drink name loyalties. I'd like to point out how New Mexico and Nevada are STRONGLY divided within their very own states!
