I thought the map was good in general without nitpicking. If I'm going to nitpick, if you add Old Industry and Up North to the Midwest, it's basically the definition I gave the Midwest earlier. (North of I-70 between KC and Pittsburgh.) I'm not going to comment on anything in the West. I think you include Texas, but it goes up to Tulsa and OKC, and over to parts of Arkansas. I like the Gulf Coast, but probably stop around Gulf Shores. The Gulf Coast part of MS and NOLA are really "Cajun" I'd not have any category that is Florida. I'd have "Miami" in the south, and then the rest is just the South. I'd also have some different subcategories in the Down South area. I'd have the "Deep South" which is MS, AL, GA, and SC. Then I'd have the Mid-Atlantic which are those portions of NC and VA currently in the South. Then I'd have the "Mid South" Which is the South portions of TN, KY, OH, IN, northern Arkansas, Southern MO and Southern IL.
But in general, it's a decent enough map, that if you include Old Industry and Up North in the Midwest, has basically gotten it close to correct.
That's fair. I would say old industry and up north are sub-cultures of the midwest. There just isn't enough difference there IMO to say they are a full culture.
I would probably take it west a little further to eastern Dakotas and all of Minnesota.
I can see the argument against Southern Indiana due to the southern accents you sometimes see there but it's kind of a battle ground there as well as Cincinnati and even maybe Louisville.
Cincy to me feels very midwestern. Skyline chili doesn't seem like a southern food to me, seems like a midwestern idea. I still get a midwestern feel in Louisville but it disappears soon after that as I'm heading south.
