Ha! That was a fun one! The quiz nailed it too. They had Wisconsin and western Michigan dark red at the end, and said I speak most like I am from Madison, Milwaukee or Grand Rapids. And I am in fact from Milwaukee. The word "bubbler" will give us away every time, lol.
As an Englishman I found the results of this test to be most intriguing, Almost the entire western area of America was dark red, those islands at the bottom left were orange-red and the coastal area in the north east of America was yellow/orange.
My three cities are Honolulu, Los Angeles and Rochester.
It pretty much pegged me too. It named my three cities as Louisville (KY), Lexington (KY), and Little Rock (AR). I live about 110 miles south of Louisville but still in the darkest part of the red band.
