Hmm... I don't think I should start putting cities in as that would take forever as most of the time when I travel I go to multiple cities...

Countries I been in:
Finland
Sweden
Norway
Denmark
Estonia
France
England
Germany
Spain
Greece
U.S.A ( California, Oregon, Washington, Florida and Hawaii. Nevada, Colorado, Massachusetts and New Jersey if you count airports )

And also Belgium and Netherlands if you count airports.
