Screw that scoring system, I'm inventing my own based on how awesome the locations were.

Barcelona, Spain
Gran Canaria, Spain
Bern, Switzerland
Basel, Switzerland
Scotland (roadtrip, no cities)
Crete, Greece
Buenos Aires, Argentina
Riga, Latvia
Tempe, Arizona, USA
La Jolla/San Diego, California, USA
Los Angeles, California, USA

So unless my calculations are wrong, I count 371.4 states' worth of travelling.
