Mayor Rahm Emanuel wants to thank Chicagoans for their patience while world leaders were in town for the NATO Summit.
Chicago closed roads, stationed police along Michigan Avenue and put security restrictions in place for the weekend. Many avoided the city completely as non-permitted protesters took to the streets.
On the last day of the summit, Emanuel all in all commended Chicago, police and city residents for a job well done.
He appeared at the Roosevelt CTA station during the Tuesday morning rush hour to show his appreciation.
"Thanks for everything," he told commuters, shaking their hands.
Chicagoans showed their appreciation in return. One woman told Emanuel "great job."
"You did a great job," another commuter told the mayor.
"The whole city did," Emanuel said in return. "The whole city did."
