Watching it now, I've never seen MR in action but I could have recited his join up spiel from KM clinics and his book.
I have nothing against any method that makes life easier for all concerned but I'd love to see this on, say, a really wild (feral then) horse/pony rather than a mare that has a lovely trimmed tail and is obviously handled.
Driving a team of 4 now, I'd tie them in the biggest knot if I did that! Very impressive.
I know- brought a lump to mine too! She was having to do exactly what I had to do with Fal with the leaning over and the circles... could SO relate to how she was feeling, it's terrifying! Fantastic to see them having a good blast at the end!
