I used to go to the circus a lot as a kid. Sadly I haven't gone to a circus like event in years. I want to go to a circus featuring animals. I like to see Lions, Bears, Tigers, Elephants and other animals, and I'm willing to bet my son will also enjoy it. Do they even do circuses anymore?
If you are a fan of the circus then you might try catching one of the circus acts at the Circus Circus casino. They have clowns, jugglers, trapeze tricks, etc but no animals. The closest you might find in animal shows would be the MGM Mirage with Dolphin shows
I can't say this is something I ever went to see in Vegas. I watched a few as a kid but with all the animal abuse and other issues that have piled up over the years, it really put me off from wanting to see them as an adult.
