silly historial fact: circus rings have been the same size since Roman times. Traditionally thay are made in 4 to 8 sections which hinge together. Horses are trained to a specific number of paces around the ring, which enable the riders to time trick rides and so on. Circus horses came from all breeds, but over the years have been bred together to make specific circus horse breeds including the Showstepper and the Rosinback while we're at it .. remember to make a wild animal cage for the big cat acts.
