I've always thought that adopting the accent of the place you move to has more to do with the person's personality than anything else. My sister grew up, went to high school, college and worked in the midwest before getting married and moving to Georgia. She was a teacher and spoke quite well before she moved. Within a few years she had a perfect Georgian accent. It fades noticably if she comes back home for a couple of weeks. If I moved south I don't think I could change my accent if I wanted to.
