This Saturday, the USOC will make its long-awaited decision: either Los Angeles or Chicago will be named the American bid city for the 2016 Olympic Games. Delegations from both cities will travel to Washington, D.C., this weekend to give their final, 40-minute pitches before the USOC. The showdown pits L.A.'s climate, Olympic tradition and existing venues versus Chicago's enthusiasm for what would be its first Olympics (it was robbed of the 1904 Games by St. Louis) and its compact footprint for the venues. The IOC will select the Olympic city in 2009.
