I really enjoyed this quiz and this is very accurate. Most of what I got was the Southern California area and my red area is highly concentrated on California. I grew up in California and then lived in Arizona so, yeah. Apparently, I don't speak Wisconsin or Minnesota English. It would probably be a foreign country to me there.
I don't get why Hawaii is not on this list since I got family in Hawaii too and their accents and way of speaking is totally different in a way that is hard for me to explain, you gotta hear it for yourself
