Win tickets to Ringling Bros. Barnum and Bailey Circus

I remember going to the circus when I was little. The Ringling Bros circus always came through Wichita throughout the eighties maybe every two years or so.  It had to be the most exciting, thrilling thing I have ever experienced, and now that I have my own kids, I want them to experience the circus, and experience it the "Ringling Bros." way.

Called the Greatest Show on Earth, this current tour is called FULLY CHARGED, Gold Edition. "Superhuman Athleticism and displays of animal magnifigance" to be found at this show for "Children of All Ages".  Appearing at Intrust Bank Arena from May 30-June 2nd.  Tickets are still available and you can enter now to win 4 free ticket vouchers.
