I took it and it said "Inland North" to which I said "Riiiiiiight" - the most time I spent there was 10 months in southern Ohio. I grew up in Virginia and still have a bit of accent although I've moved around a lot (California and Europe (Germany, Italy, and England)) and now live in the Northwest. Another factor may be that I sing chorally and always try to enunciate clearly so that it's natural to me to always do that, even in speaking.

I gave the quiz the worst rating possible as it doesn't seem very accurate. Still, it may work for people who've lived all their life in one location.
