Chicago Cubs fans are turning their attention to the World Series for the first time in 71 years. Overjoyed fans streamed out of Wrigley Field and into the streets Saturday night in Chicago after the Cubs beat the Los Angeles Dodgers in Game 6 of the NL Championship Series to earn their first trip to the World Series since 1945. ''I never thought I'd see it,'' said 49-year-old Brian Dusza, who also was at Wrigley Field for Game 6 of the 2003 NLCS.
