The 28th annual Green Tie Ball went down on Friday, September 13 at the Alhambra Palace, with co-chairs Grant DePorter, Lee Golub, and Fall Out Boy's Pete Wentz mingling with 1,000 guests throughout the night. Through ticket sales, a fast-paced live auction, and games provided by Rivers Casino, the evening raised more than 200,000 for Chicago Gateway Green, which helps to beautify miles of the city's freeways.
