We all know that Transformers 3 is being filmed in Chicago amongst other locations around the country and the world thanks to a recent post by Michael Bay. The dream came one step closer to reality for Chicago Transfans as Collecticon.org received confirmation from an un-named source that businesses along Michigan Avenue are being pre-emptively notified of an upcoming shoot for the movie.The phrase "Magnificent Mile" refers to a portion of North Michigan Avenue. I know nothing about Chicago but Google Maps might help give you an idea that is under discussion for the film.
