Closest county to where you live that you haven't been

[True Federalist (진정한 연방 주의자)]

As I have never been to the USA: Aroostook County.

You've been to every single British and Irish county?

European posters shouldn't assume that the closest county is Aroostook, Maine. It's true for Germany, but some parts of Southern Europe, like much of Spain and Portugal, are probably closer to Washington, County, ME, and parts of Scandinavia, like Helsinki, Finland, are closer to North Slope Borough, Alaska than anywhere in Maine.

For the northernmost part of Scandinavia it is indeed North Slope borough and also regarding Helsinki you're right, but if you go to Oslo the nearest U.S. county is Aroostook again. The same applies to London and Istanbul.
When it comes to the closest U.S. county to Lisbon, Washington County, Maine, is winning by a grain.

I repeat.  For our European posters, their closest country they've never been to is probably one in Ireland or the United Kingdom.  For that matter, Nova Scotia has counties as well.

Now we've come to a question of linguistic philosophy.

True, but under either point of view, is a county only something called a county or is it any second-level administrative division, there are counties closer to you than those in the U.S.

Incidentally, in SC law, towns and cities are all municipalities which get to choose when they incorporate which title they take.  The smallest city is Chesnee with 868 people in 2010 (down from a peak of 1280 in 1990) while the largest town is Mount Pleasant with some 67,843 in 2010, up from 6,155 in 1970.
