I definitely have a weird deal where I mimic accents of whoever I spend time around, it's totally unconscious. But my base accent is rural BC (sort of like California x Minnesota) plus NC vocab as well. It's a mess.
Im in a similar boat having loved so many places. I did the quiz/map exercise but didn’t screenshot it because mine was ridiculous. My triangulation places were Mobile, Montgomery, and Columbus, GA.
I mean you’ve heard me speak, like wtf?
