Inaccurate Map I do not understand why northwestern Indiana is only colored brown on the map to the right side of this article  I met a man just the other night from Michigan City and he diphthongized  to e or something similar in his speech  I think northwestern Indiana should at least be surrounded by the red line maybe even all three lines  I dont grasp how the Indiana border signifies the terminus of the core of the NCVS yet the Wisconsin border with Illinois does not  This area is mostly part of Chicagoland so I dont see why the people there would speak a different dialect excluding the speakers of African American Vernacular English who make up a majority of the population in Gary among other places in the region than those in the Illinois and Wisconsin part of that region  Also one with a keen eye will notice that northwestern Indiana is included as part of the core in the Inland North article it is highlighted in blue however it is not enclosed by all three lines on the map in this article  This needs to be fixed
