It was the 7th largest human gathering in history. A victory parade for the World Series champions, the Chicago Cubs, which attracted a bigger crowd than the entire New Zealand population.
And the All Blacks couldn't help themselves, getting amongst all the action in Chicago.
It was a slight upstaging to their 2015 Rugby World Cup victory celebration. That attracted just a few thousand supporters. But exactly a year later, they were able to witness what it's like to celebrate with millions.
The parade left Wrigley Field under clear blue skies and players took turns holding up the glittering World Series trophy as the procession made its way south through miles of downtown streets before ending at Grant Park where a free rally was held.
Barrett, Smith, Perenara and Savea were snapped among the estimated five million-strong crowd of roaring fans in the city's Grant Park celebrating the Cubs' first World Series title in 108 years.
