I was watching RFDTV for the Roses Parade and drill teams and such kinda like a pre show. Most horses were pretty well trained but a few had tie downs on, there mouths gaping and fighting the whole way shaking there head back and forth. It was upsetting to see this kind of horsemanship or lack of at this kind of an exibition.
I am guessing the fellow riders are not brave enough to tell them they have a training problem and help them.
This was disturbing to me and I felt very sorry for the horses as they looked very distressed.
