86% here, even though I was born in Miami Beach in WWII, grew up in Indiana, then lived in Ohio, FLA and CA, but ended up in Virginia.
Now lived here way more than half my life & guess I’m converted.....All my northern friends say I have a southern accent......
Shucks.........I sure can’t detect it!
Born/raised in NY, but in VA now 48 years, and got 100% southern. Sure to make my NY relatives crazy (jealous crazy).
