" In 2002, Soldier Field, the Chicago Bears home, urgently needed upgrades to modernize the stadium, which was built in 1924. Renovation costs were $587 million in total. The NFL and the Bears organization chipped in $200 million toward the work, and the city of Chicago financed $387 million through municipal bonds levied by a tourism tax in Chicago. According to an investigation by NBC Chicago News, 20 years after the renovation, Chicago owes $640 million on its initial $387 million bonds after years of deferring payments. The city declined to comment to NBC Chicago."
