When attendees at NAFCU's annual conference spend Friday afternoon watching the Cardinals-Cubs game, they will see a part of history in the making. The teams compete for loyalty among fans and rich histories that are rife with symbolism.

In his 2005 book on the rivalry-3 Nights In August-Pulitzer Prize-winning author Buzz Bissinger wrote that the rivalry between the teams is "probably the oldest and perhaps the best in baseball, no matter how the Red Sox and Yankees spit and spite at each other."

One team-the Chicago Cubs-is the quintessential symbol of the little guy who keeps trying hard and is lauded for a fighting spirit and for being lovable. Even though the team has gone 102 years without a championship, there are often sell-out crowds at their storied 97-year-old Wrigley Field. It is the second oldest ballpark after Boston's Fenway Park.
