Chicago Tribune article about the new West Building at the McCormick Place Convention Center sure makes me wish YearlyKos had been held there rather than in the "even-larger South Building, which flaunts a grand concourse that's more than twice as high as the one at the United Terminal at O'Hare International Airport" and managed to be so enormous that it made a very large gathering feel dreary and empty all the time.
