The target probably isn't any more significant than it being roughly the middle of North America, I'd bet there is a map of the USA with a dart hole in Eastern Iowa in this guy's posession.
The writing style strikes me a incredibly typical of the mindless freshman and sophomore screeds written to and ocassionally end up in the editorial section of college newspapers. The "I've lived here for many years" strikes me more as his proclaimation that he isn't a kid more than an admission of being a foreigner. The various civilizations remark also strikes me as a juvenile attempt at appearing knowledgable.
But hey, I could be wrong.
