You can find the AMHA Special awards in the downloadable World Show premiums on the AMHA website. I think they are located in the Archives under the Show and Show Results section.
This year, the Moonlight Bay/High Point Driving Horse award was won by SSH Shadow of a Doubt, owned By Linda Nelson of Oklahoma... He also won the Best All Around award, which if I heard correct, was the first time in AMHA history that a horse has won both awards in the same year.
I think the Super Amateur went to David Sandeno... I missed the Ammy awards, but I thought thats who I heard won it.
