When I read your comment, I couldn't resist trying. I wrote down all but one off the top of my head. Why have I never heard of Nunavut? Did it used to be called soemthing else?
I certainly noticed that, because I used to watch movies so much and haven't in the last ten years since the kids arrived. I don't think its neccessarily because the movies are not as good these days (like I would know), but it takes quite a few years for any movie to achieve "classic" status. How well a film holds up over time is important.
To be honest, this isn't exactly a "top ten" list, because its so subjective... and also because there are so many extreme sports that I may do up another ten soon!
I had considered both spellings, and went with the one a non-Chinese speaker would more likely try to pronounce. Someone who speaks Chinese would recognize the attempt!
