36/45 - avg 29 miles. Some fairly obvious - most of mine were a bit out in Eastern Europe, but if people do not know where, say, France or Italy are, there is really no hope!
Jabber - if you mean places like Monaco, Andorra and San Marino, thay are countries, but very small ones. Luxembourg is also a country, and its capital city is also called Luxembourg - lovely place and cheapest petrol in Europe
