For me, to find a place that doesn't have an organized tour going to it is becoming more and more difficult. A lot of times it involves danger of a political nature - places where the adventure-travel trips can't go because they can't get any liability insurance.

A lot of the physical flirtation with fear I did early on in my career, when I was a much younger person - stuff I wouldn't do now. But I was very interested in the mechanics of risk and fear in those days. And I found out fear pretty much always feels the same, whether it's doing a rock climb or speaking in front of an audience.

My idea of a vacation is staying home and doing short day hikes, floating the river and things like that.

My first real writing job was at 'Rolling Stone,' so I wrote about rock-and-roll and politics and the like. At the time, I really didn't know what I wanted to write, and I did a bunch of investigative journalism.

When you've managed to stumble directly into the heart of the unknown - either through the misdirection of others, or better yet, through your own creative ineptitude - there is no one there to hold your hand or tell you what to do. In those bad lost moments, in the times when are advised not to panic, we own the unknown, and the world belongs to us. The child within has full reign. Few of us are ever so free

A constant ongoing joke among the people that I travel with is my absolutely hopeless sense of direction. I'm able to get lost a half an hour from camp. I don't know how I do this.

You have to first be a writer and somebody who loves to write. If I couldn't travel, I would still write.
