Her body language and how the horse reacts tell me all I need to know. Honestly. It is dangerous, of course, as all things we do with horses, but in the right hands and in the right time this is a wonderful tool to strengthen partnership. I see that this girl knows what she's doing and I respect her for her choices. Many of us would have lots to learn from her - and it's a shame that just because there are inexperienced people out there, who post truly dangerous videos that show their incompetence, examples of true work at liberty get stashed in the same pile.
I have come a long way, to surrender my shadow to the shadow of my horse.
