Yeah, it's no joke. Beijing's 2008 Olympic was a success, but the Chinese government had a colossal undertaking to made it work, including suspending local factories for production and lessen traffic in order to reduce the smog and emission level in the city; shipping water and food from other provinces to ensure that they stay healthy for the Olympians (at the expense of their own people); and had the city turned into an almost police-state to block out the protesters and potential terrorists, or anything that would ruin the party and make China look bad. I doubt Chicago can bend itself backward to make the city that hospitable.
