Atlanta will get "their first -- and last -- chance" to test their ability to hold a major international event when as many as 1,000 Olympic officials and guests visit. While the Association of National Olympic Committees (ANOC) and the IOC hold a joint convention this week, ACOG will test "all the Olympic systems -- from accreditation to transportation and security" (Melissa Turner, ATLANTA CONSTITUTION, 12/10). Charles Battle, ACOG Managing Dir of Int'l Relations: "Atlanta is not a well-known place, this meeting is a tremendous opportunity for us." In addition to touring venue sites and attending to other logistics, the group will address the "explosive growth" of the Olympic movement. Since 1992, more than 24 new countries have joined; Atlanta expects 196 in '96 (Elizabeth Kurylo, ATLANTA CONSTITUTION, 12/12).
