The Exotic Travels through Indiana

So as I am driving north from Bloomington to Elkhart this past fall, I noticed something very odd. Not only did I drive through the cities of Kokomo, Miami, and Denver, but I drove through (what I believe to have been the cities of) Peru and Mexico. Now I dont know about you, but why in the HELL would you name ANY part of Indiana after ANY of these cities/countries?!? Granted, Indiana might be as hot as Kokomo would be in the summer, or as cold as Denver in the winter, and be as humid as Miami in the summer, but why Mexico and Peru?!? I've been meaning to post this for a while, but ya, just letting out some steam! Let me know what you all think!
