As a veteran road-warrior I've covered stories from Antartica to Afghanistan and hundreds of places in between. Each story, each shoot, each interview brings its own challenges.  Whether the story means sleeping in a shallow fighting hole during a sandstorm while embedded with the Marines for the invasion of Iraq, keeping camera batteries warm under my jacket shooting at the South Pole, swimming deep into a jungle cave in Belize to explore the remains of a long disappeared Mayan cullture, traveling with actor Don Cheadle on a difficult and wrenching journey among refugees of the genocide in Sudan or just sitting down with the Dali Lama in a hotel room to talk about the path to happiness, every story I've covered has taught me a bit more about the world and our place in it.
