"even" you say. I live in a not small but not that kind of a big country and you get out of the coastal cities and you end up in whole another culture. I don't know the exact reasons but where sea exists, I feel home. 150-200 kilometers outside is completely different.
I guess in my country, where people originally came from has to do with this topic. Coastal areas generally has people from Europe, other areas from Eastern countries, etc.
Damn that’s another really good point I hadn’t thought about. I wonder if bordering areas of countries (with land masses on the other side instead of an ocean or sea) also have pretty significant cultural differences compared to more inland areas
