So I'm thinking ahead to show season. I go to some open breed shows with a friend and ride his Arab western pleasure horse. I'd like to take my own horse along this year for some hunt seat classes. He's a TB dressage horse and I thought it would just be a fun change of pace for us. I'm trying to figure out what classes we would be eligible to enter and there are a couple that I'm just not sure what they are. Can anyone explain what would be required in open english road hack horse-saddle seat or hunt seat? Also bridle path hack horse-hunt seat?
