CHICAGO

In my opinion the video of chicago was very interesting. Chicago is one of the most important cities of the United States and is famous for the skycrapers. The video showed the most important buildings (sears tower, teather, auditorium,etc.) They talked about the fire in1871 and how the citizens of Chicago quikly began to rebuild the city after that disaster, that's what i liked the most!
