I can't tell if you're being sarcastic or not. Jackson, MS is 80% black while Portland, Maine is 1/3 the size and almost 90% white. I bet you'd find grits as readily in Portland as you'd find lobster rolls in Jackson. Summer daytime high in Portland is about 15 degrees cooler on average than Jackson; in the winter, it's more like 25 degrees. Portland averages 60 inches of snow per year; Jackson almost never experiences snowfall at all. If there's anything I've learned traveling both around the US and abroad, it's thst the variation within the US is almost as extreme as between the US and abroad, in terms of climate, topography, people, and urban design. Sure, some suburbs in Illinois look a lot like suburbs in California. But Stanford's campus is drastically different than Cal's, just as Notre Dame's is from Miami's.
