Hrm. I've only been to 20 of the 812 World Heritage Sites.
What makes the concept of World Heritage exceptional is its universal application. World Heritage sites belong to all the peoples of the world, irrespective of the territory on which they are located.
It's definitely time for more travel.
Why don't you come with Janine, me, and the kids to South Africa next July, you could hit a few of the sites :-)
Don't tease me!
