Hmm. I'll have to see if I can track down a video. What I was watching today on RFD TV was called "Horse & Country" and it was a British (I think) guy doing a dressage demonstration.
I also heard it on a video that was posted here at the horse forum a while back. I *think* it was perhaps Anky(sp?) when she was demonstrating long and low, or long and deep, or rolkur? I dunno, I get all the dressage stuff in a jumble! But the dressage people seem to do it the most.
If I find a video I will post it. But if anyone else knows of a video offhand and wants to post it, that would be great too!
