`  ==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 /æ/ to [eə] 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 don't 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 don't 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.      `
