Games Pony Wanted

I'm looking for a new games pony for my daughter. She is a D2/D3 level rider, 11 years old and pretty small. She can handle some speed, but needs good brakes and a good disposition. Should be medium and able to do both games and trail-riding. Sadly, her current games pony is nearing retirement due to arthritis in the hocks . . . If you have any leads, please let me know. thanks, Cyndi D. (609) 466-0895
