Years of walking, Karl Bushby has overcome jungle, desert and red tape. Now he's nearly home

Karl Bushby is nearing the end of a 28-year walk home from South America, but with about 50 kilometers (30 miles) left in northern England, he still sounded unsure about returning to normal life. The 57-year-old pushed a cart with camping gear up a busy country road as he approached the finish Monday in Market Rasen. Starting on Nov. 1, 1998, when he was 29, Bushby has covered about 31,000 miles (50,000 kilometers) across four continents. His “Goliath Expedition” included navigating the Bering Strait’s ice, swimming across the Caspian Sea and English Channel, and dealing with a polar bear standoff.
