But, but... a lot of californians are from elsewhere.
I was born there and lived there almost five decades. I met some a2k friends in New York, and they said I had some eastern sounds to my voice, namely Boston, where my mother was from, though I don't detect that myself. I think I also may have some Chicago in my voice (lived there five years as a kid.) I also lived in the Bronx for a year, and doubt that I have any Bronx in my voice. Anyway, Californians don't sound alike to me.. but this has got me curious about what you folks are calling California accents.
Meantime, my husband the playwright used to straighten me out that accent wasn't the right word, that what I meant was dialect. (I still think he's wrong about that, but he's the one who took all the speech and rhetoric classes).
