FORT MYERS, Fla. It’s the end of an era. After 146 years, the “The Greatest Show on Earth” will entertain one last crowd this weekend before the curtain comes down for good. The iconic Ringling Bros. and Barnum & Bailey Circus is permanently shutting down due to high operating costs and the decline of ticket sales. Dean Kelly and Taylor Albin, two former Ringling clowns and current Southwest Florida residents, are still shocked by the circus’ closure. “With something that’s around that long, you think it’s going to be around forever,” Kelly said. Kelly and Taylor said a lot of work went into putting on the shows, including at least 10 weeks of planning and rehearsals. “Bringing joy and laughter to people all across the nation was so incredible and so rewarding,” Albin said. “I absolutely loved every second.” The Ringling Bros. will perform their final show at the Nassau Coliseum in New York Sunday at 7 p.m.
