I will be doing a Conversation with him, here is Wikipedia:
Paul Salopek (born February 9, 1962 in Barstow, California) is a journalist and writer from the United States. He is a two-time Pulitzer Prize winner and was raised in central Mexico. Salopek has reported globally for the Chicago Tribune, Foreign Policy, The Atlantic, National Geographic Magazine and many other publications. In January 2013, Salopek embarked on the “Out of Eden Walk”, originally projected to be a seven-year walk along one of the routes taken by early humans to migrate out of Africa, a transcontinental foot journey that was planned to cover more than 20,000 miles funded by the National Geographic Society, the Knight Foundation and the Abundance Foundation.
Salopek received a degree in environmental biology from the University of California, Santa Barbara in 1984. Salopek has worked intermittently as a commercial fisherman, shrimp-fishing out of Carnarvon, and most recently with the scallop fleet out of New Bedford, Massachusetts, in 1991. His career in journalism began in 1985 when his motorcycle broke in Roswell, New Mexico and he took a police-reporting job at the local newspaper to earn repair money.
As far as the walk goes, he has made it to China. So what should I ask him?
