Indiana is home to an amateur circus. Every year in July they perform for the public, and then wrap it all up with the largest annual circus parade on Earth.
Organizations like PETA have have been protesting the use of wild animals in the circus for a long time. The animals play a major role in any circus, in particular, the elephants and the big cats. More often than not, the performances go off without a hitch, but sometimes the animals don't want to perform and that can be scary.
