The thing is the BO said that this is too much to expect of "A" horse, not just her horses. And the people in this group all said that too.
It would be one thing if they said, "Oh no you can't do that with these horses". They said that's too much for any horse. That's why I walked away thinking that I was expecting too much when the time comes that I do buy a horse.
I DO want to try cantering on the trail as it does seem like fun. But I want to know that I could slow down my horse if I didn't feel comfortable. That's not going to happen here.
Bsms, that is a good point that you mention about a leader horse. The horses that I ride aren't really what I'd call leaders. They are definitely followers so I know that if the other horses take off, they will too. I can see how a horse that is more of a leader could be content doing its own thing.
