Great quiz. I really like you "5 closest to:" series. A question about the Kara Sea. Would Canada not be closer than Kazakhstan if you go "over the top"? Ellesmere Island extends pretty far north assuming you measure from the most northerly boundary of Kara Sea.
Bloody hell, you really need to accept 'RoC' as a type-in for Taiwan. I thought I'd already guessed it, and kept frantically searching for other countries it could possibly be.
