The lack of demarcations that correlate at all with major economic area distinctions is a red flag to me that this map is questionable. There's definitely a big cultural distinction between the Boston/DC corridor part of the east coast states and everything else in those states. DC has more in common with Boston than DC has in common with other parts (e.g. Indiana) of the "midlands" panhandle the map has it occupying. The fact that there's a line smack through the DC metro itself is kind of a wtf. There should probably be "left coast" dots for the counties that Denver, CO and Austin, TX are in. Maine North of Portland has more in common with Quebec and western Pennsylvania than it does with anything in Southern New England. If those are my gripes based on my personal experience then I would wager the areas with which I have no experience are similarly inaccurate. Edit: Just confirmed with people from Michigan, Indiana and west Virginia. They all had some pretty raised eyebrows at this map. Edit2: Asked some Mainers, one called the map "bold".
