Ya'll are about to get on my last Hoosier nerve.
This may come as a shock, but people who hail from big cities can be just as provincial and ignorant of other cultures as their counterparts in minor metropolises and tiny burgs. Most people I have encountered in small cities are aware of their homes' limitations. They understand that they will have to look beyond their borders for some things. By contrast, many big city dwellers I've encountered believe
everything exists where they are (the smartest people, the best food, the best art, etc.) and that there is no need to look beyond their borders for anything. And so there arises this idea that everything between coastal urban centers is a sea of lack and strangeness. And, for Chicagoans, the same goes for anything beyond the approved (white, wealthy) suburbs of the Windy City.
