John Holmes and his game chestnut Gideon had plenty of good news at the Plymouth Rock Hunter Jumper Classic. They started the week of June 21-25 with victory in the $7,500 Welcome Stake and finished it by taking home the top prize in the $25,000 Grand Prix. The show was a first-time “AA” competition held at Fieldstone Equestrian in Halifax, Mass., and jumpers competed on the grass grand prix field.
