It would be nice if this supported continents beyond the following (taken from the source code):
- Europe
- North America
- Asia
- Additional cities in Oceania
- Additional cities in Africa
- Additional cities in South America
- Additional cities in North America
- Additional cities in Japan
- Additional cities in South Korea
If you live in a city of more than a few hundred thousand in Africa, Oceania, or China, you're out of luck!
