Travels

I love to travel, probably more than most other things. I feel that my education in geography and world history was sub-standard so I'm hoping to make up for these deficiencies by visiting as many countries as I can to better understand them from the perspective of people who live there.

Thus far I've visited 21 countries. They are:
Cambodia
Vietnam
Thailand
Lao
Malaysia
Indonesia
England
France
Scotland
Ireland
Germany
Switzerland
Austria
Greece
Italy
New Zealand
Australia
The Netherlands
The US
Canada
The Vatican

This summer and fall I'm visiting Ghana, China, Switzerland (again), Hungary, Croatia, Slovenia, Poland and the Czech Republic. 

The view over Salzberg from a nearby mountain in the Alps.

I'll have two more to go to attain 30. Which ones should I choose?
