I'm a New Zealander, so I make no apology for starting with my own beautiful country. These are (nearly) all the places I've visited around the world. Much as I would like to roam around Africa and the Americas, or visit Antarctica, I haven't done that yet. Hopefully there will be plenty who take this challenge who can get way more than the average 25/200 that you see in other lists. Good luck!
The title photo shows Rangitoto Island, the symbol of my home city of Auckland. It's the largest of more than 50 extinct volcanoes within the city boundaries.
