Well, I am from southern California!
This is highly entertaining. My score was "52% (Dixie). Barely into the Dixie category", which is amusing, as every one of Chris' friends and family think I sound totally Californian. Perhaps if one of the questions had asked how to pronounce rain, I would have done better. (Correct answer for a southern Californian, by the way, is "huh, so that's what you call that stuff!")
