PITTSBURGH– After passing a haggard-looking Japanese man on the street Monday, area resident Gary Webber concluded that the guy must be some sort of artist or poet or something. "Normally, you see a guy dressed in a dirty, ripped coat with his hair all scruffed up, you figure he's just poor. But this guy was Japanese," Webber said. "I bet he's in town to do some kind of art opening. Or maybe a book signing. Whoever he is, he's got to be somebody."
