Ravinia has signed on as a sponsor of the Feb. 23 TEDxWindy City event that will bring together a variety of TED Talks speakers to address the theme “contrast.” As part of its support, Ravinia will recreate one of its glorious lawn picnics for the lunch hour. “How can a place like Ravinia—known for being something different every day—not embrace the concept of contrasts?” asked Nick Pullia, director of communications. “Ravinia, home of the cultural omnivore, is a series of contrasting opportunities: Pavilion or lawn? Classical or country? Picnic or fine dining? We thrive on contrasts.” The event runs from 9 a.m. to 5:30 p.m. Saturday, Feb. 23, at Northwestern University School of Law in Chicago.
