Aside from your country of residence, of course.
And by "been to", I mean on the ground. Airports DO count! After all, if you get off the plane and punch someone in the face, you will go to the local jail, under local laws.
My list:
Netherlands
Italy
Kuwait
Croatia
Saudi Arabia
Qatar
United Arab Emirates
Canada
Greece
Turkey
A rather small list I know, but my wife and I love to travel, so we hope to add to this in the coming years.
