I was having a conversation with someone the other day and was explaining that I lived on the coast. They politely responded with a question wanting to know if I lived on the East Coast or West Coast. I advised them that I lived on neither the East Coast nor the West Coast, but firmly was planted on the South Coast. This immediately brought up questions about what the South Coast was and they explained that they did not know that the US had a southern coast.
