The big top is back in Troy’s Prospect Park.

Troy’s Contemporary Circus is wrapping up its two-week run with a three-day headline performance this weekend. “The Rainbow is Enough” features aerialists, juggling and acrobatics in a 60-minute show. Organizers say the goal of the nonprofit circus is to highlight American performers and introduce the circus arts to the next generation.

The show starts at 7:30 p.m. Friday, Saturday and Sunday. Tickets are free on a first-come, first-serve basis. For more information, log on to www.CCIAC.US.
