In Paul Salopek's first year of his trek across the globe, the reporter walked alongside his camels for days in Ethiopia without seeing glass or bricks or any other signs of modern humanity, ate a hamburger on a U.S. military base and was shadowed by minders in the Saudi desert. He has only 20,000 miles (32,000 kilometers) to go.
Salopek is walking from Ethiopia to Chile, a seven-year journey that aims to reproduce man's global migration. Beauty and difficulty filled his first year, which is now nearly complete. In his second he will skirt the violence of Syria but will cross Iraq and Afghanistan. (Associated Press)
