Major construction during Daley's terms in office resulted in O'Hare International Airport, the Sears Tower, McCormick Place, the University of Illinois at Chicago, numerous expressways and subway construction projects, and other major Chicago landmarks. O'Hare was a particular point of pride for Daley, with him and his staff regularly devising occasions to celebrate it. It occasioned one of Daley's numerous clashes with community organizer Saul Alinsky. His black-neighborhood Woodlawn Organization threatened a mass "piss in" at the airport (a crowding of its toilets) to press demands for open employment.
