I also agree that these sessions should not be invite only or by some private selection system. That I think can be changed immediately by possibly selecting horses that have some qualifying scores in local YH classes...video might be hard as you need someone to watch all those videos. Qualifying scores are an immediate weeding process. Then those selected horses can attend training sessions before another show opportunity or championship class.
However, finding someone else to prepare, organize and develop this program may prove quite difficult.
What are the differences in how the YH programs are run in Holland, Germany, England? It is easy to say our program isn't working (and I don't disagree) but what are the differences? What changes can be implemented? These points need to be elucidated to make those changes.
