Result: The WestThis is kind of funny. When I was travelling around the UK, I got complimented on my accent ("Very smooth, not at all hard to understand like most Americans"), but when I was working in Jamestown, NY (about an hour from where I grew up in PA) several people were able to place me by it.
Your accent is the lowest common denominator of American speech. Unless you're a SoCal surfer, no one thinks you have an accent. And really, you may not even be from the West at all, you could easily be from Florida or one of those big Southern cities like Dallas or Atlanta.
