Every day from 11am to Midnight above the midway at Circus Circus on the north end of the strip are free shows of circus acts.The acts are usually acrobats,clowns or tightrope walkers. If you are staying down that end of the strip it might be worth you seeing but i don’t know if i would make a trip just to see it unless maybe you had kids with you.The only clown i want to see is Krusty the Clown on the Simpsons but that’s just me.
