Photographer Peter Tsai loves everything about Chicago, but every year, one of his most exciting moments comes when the city dyes the river that runs through the heart of downtown green to celebrate St. Patrick’s day. Tsai had the perfect vantage point for time-lapse and photos from the Hyatt Chicago, and the film makes us feel like we are in the Windy City, drinking a Guinness and partying along on this Irish Holiday!
