Mike Leavitt; USOC Pres Dr. LeRoy Walker; IOC Member Anita DeFrantz of L.A.; and 10-year-old Figure-skater Cynthia Ruiz of West Valley City (John Keahey, SALT LAKE TRIBUNE, 6/14). Anita DeFrantz, U.S. rep on the IOC's Executive Board: "I have visited all four cities and they could all host the Games. The difference is that Salt Lake City has the venues now. The facilities exist" (Gordon Monson, SALT LAKE TRIBUNE, 6/13).
