The Big Top is coming down on The Greatest Show on Earth - Ringling Brothers and Barnum & Bailey Circus is closing for good later this year. The owner, Feld Entertainment, cites a number of factors for closing the circus, but Chief Operating Officer Juliette Feld says removing the elephants from the touring units was catastrophic, resulting in a very sharp drop in attendance. Other factors include high operating costs and long battles with animal rights groups. The last show will be at the Nassau Coliseum on Long Island on May 21st.
