Seems like a cool idea. Should Chicago get the 2016 Olympics they might use London's 2012 Olympic Stadium! London would recoup some of the money spent on building it and Chicago won't spend as much on building a completely new Stadium. I don't believe the entire stadium would be moved, but at least 55,000 seats and other sections would be dismantled and shipped to the next host city.
