The most frightening interview I've ever done was with Dr. Lonnie Thompson of The Ohio State University on the subject of global warming.

I think there's value in experience and observations that link past to present.

My personal philosophy is I'm running a 100-yard dash, and I haven't reached the end.

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.

Frontline' does 10 news shows a year, so one a week is quite an undertaking.

A journalist enjoys a privileged position. In exchange for not being able to participate in the rough-and-tumble issues of a community, we are given license to observe it all, based on the understanding that we'll tell everyone what happens fairly and squarely. That's harder than it sounds.

That's the reason I left the networks. I wanted to write and report and coanchor.
