Recently, the Long Shot went up the Amazon River. While he doesn't speak Portuguese, he knows the names of the obscure insects, menacing reptiles, mythical fish, wild cats, and monkeys. He has also become familiar - in a strictly reportorial sense - with an array of young women in miniskirts and "Rockstar" tees. He also had, briefly, an amoeba living in his intestines. Here is the photographic evidence, including shots of his subject, Martin Strel, a crusty, portly 52-year-old Slovenian who is swimming the entire 3,375-mile river, from Atalaya to Belém.
