But the Incas have the Andes mountains that are wrapped up right against their shoulder. I mean, Incas were in the Peruvian area, kind of that western edge of South America. And the Andes run kind of straight through that western side. So the problem is you have a lack of cultural diffusion. You know, cultural diffusion is like gas that keeps you going. New ideas, raw materials, new products, new ways of thinking, new languages, you know, meeting other kinds of people, developing alliances. It's good to be able to have cultural diffusion.
