Chicago, site of AUA's 2003 annual meeting, offers attendees and their guests an almost endless assortment of cultural, entertainment, shopping, dining, and recreational activities to occupy their free time. Visitors benefit from the large range of choices found only in a big city but will feel welcome wherever they go, thanks to Chicago?s brand of Midwestern friendliness.The nation's third-largest city is home to the world's tallest building, North America?s biggest convention center, and the nation's second-busiest airport. Yet despite its size, enjoying the sites in Chicago is easy since most key attractions are located within a several-mile radius of the downtown area and are readily accessible through public transportation. Choices of activities appeal to tastes running from the sophisticated to the casual.The Chicago Cultural Center (312-346-3278) may be a good place to start because it is home to a Chicago Office of Tourism Visitor Information Center. Formerly the main branch of the Chicago Public Library, the Cultural Center is a Chicago architectural landmark. A key highlight is the world?s largest Tiffany stained-glass dome. Visitors can marvel at the elegance of the building?s interior on their own or take a guided tour. Free concerts and performances are also offered.
