focal points in downtown over the ages

It seems like Chicago has some very distinct street/corridors downtown that each had there respective distinct Â"erasÂ" in which these street/sections of Chicago downtown was the focal point in town. South State Street (State and Madison in particular) had its glory days around the turn of the century. The LaSalle canyon was a predominant streetscape with the Chicago Board of trade as its centerpiece during and in the years surrounding the depression era. North Michigan Ave. began its glorious days in the 60Â's and 70Â' and continued till recent years. I dare say that the current focal point of the city is our magnificent river. With all the amazing construction and eye popping developments surrounding and lining its shores this phenomenal crossbreed between nature and man made elements is being groomed to become ChicagoÂ's greatest artery and linking point for the whole city. Building a strong bond between the north and south sides of the greater downtown area. Do you all share my views on this matter or do you feel it is off base completely? Were do you see the city turning its attention in years to come? I predict that Block37 will become the main focal point of the future (2015 -????) Do you agree with that assessment?>
