Great topic. Actually, when I started seriously thinking about this little adventure, I needed to figure out what to see. Where do you start? Where do you go first? I too had the "Wonders of the World" in my head. I'd never thought about them much - i didn't even know what the original 7 were. I just remember King Kong was supposed to be the 8th.
Anyway, i did some reasearch about a year and a half ago. There's no "official" list anymore. Groups all over the world have thier own opinions, and it's tough to decide which one I agree with most. To bypass that, I've included some links, and some of the most-agreed upon lists I found. And I say "lists" because now people have divided them up into "modern", "natural", "forgotten", etc.
When I actually took a look at the list - I realized i haven't seen much of the world. It was yet another motivator for the trip.
Let me know what you think...
