The Jaguars aren’t the only jungle animals around the Sports Complex. The “Greatest Show on Earth” pulled into Jacksonville via train and unloaded some star entertainers Tuesday. The “Animal Walk” takes place every time the Ringling Bros. and Barnum & Bailey Circus comes to town. The animals were unloaded from train cars on Talleyrand Avenue and walked down Gator Bowl Boulevard to Jacksonville Veterans Memorial Arena where the show will open Thursday night.
