The planners call themselves "Panamaniacs," a name that expresses their obsession with Buffalo's 1901 Pan-American Exposition and with its centennial celebration. And the Panamaniacs at the University at Buffalo have put together an eponymous two-day on-campus festival Sept. 22-23 in which visitors can experience the thrill of the original Pan-Am midway through films, music, foods, games and memorabilia.
