All vacations can come down to a few little moments - what do your remember when you're alone, totally relaxed and taken out of yourself to appreciate this other world.

I have an affinity for Africa, especially East Africa, and Kansas looks very much like that.

I've been producing documentaries on global warming for 20 years and have seen the early warnings of extreme weather events come true.

The prediction that glaciers will be gone from Glacier National Park has been moved up by 10 years to 2020, the same year it's predicted the Arctic Sea will be ice-free in the summer.

If you're a producer, you always spend too much money because you want that shot - and you're willing to spend a bundle to get it.

I never wanted to retire. I wanted to kind of shift my work pattern so I could stay fresh and invigorated, and use the experience that I had gained in 30 years, but in a slightly different direction.

First of all, I'm a Midwesterner, being from Kansas, and Chicago is basically a big Midwestern cow town. It was built from the stockyards, and everyone is very friendly, and it's at the edge of the tallgrass prairie. There's just a good feel to it.
