Chicago still has to introduce itself

Watching the presentation, it's hard not to notice how much time is being sent simply introducing visuals of the city and its people.  That's because Chicago is the new kid on the block... a handful of IOC members have never even been there.  A Chicago 2016 source says the delegation made the decision to bypass talking too much about the technical components of the bid... the assumption being that IOC members already understand an American city will have no problem pulling off the logistics of hosting.

That last point is a subtle slap at Rio.  Chicago 2016 Chairman Pat Ryan also just told IOC members that they'll want to bring their families to a Chicago Games, they'll be "safe," he said.  Hear that Rio???
