My first visit to West Berlin was in February 1983. The drive through East Berlin, the fact that West Berlin was surrounded by a wall that was more than 100 miles long - the absurdity and intensity of it really knocked me out.

I'm not trying to amass people in the streets. I just want them to be more aware. So many Americans, for one reason or another, they watch the news and it doesn't really give them the idea of the world. Or they don't read or travel. They have no idea that America is part of the world and not the world itself. And so anything from the travel stories I tell, that's what I'm trying to get across.

If you want to believe that humans walked with dinosaurs and the planet is a few thousand years old, that is absolutely fine with me. If you want to teach this to your kids, I don't care. If states want to teach creationism in their schools, there is nothing I can do about it, so I don't sweat it.
