Ahhhh, my instructor is one of about 7 instructors in the US trained under Monty Roberts. For more info, go to Wildewoodfarm.com.
She's great and we do clinics all the time there. I believe there is nothing better than a great Join-Up but you should read up or have an instructor to help you the first time to know what to watch for, and the proper technique. It makes my boy so much different afterwards. He has a whole new attitude towards life and being ridden. :) I'd absolutely reccommend it.
I did it with my horse a few times but he is so much of a people horse that he keeps coming back to me right away without even giveing the join-up signals! It works but the idea of having to have a round pen to do it in is rediculous, it can be done anywhere as long as you can keep the horses attention.
Masatisan, have you read the Heartland books?
I love love love those books, I've always wanted to join up with a horse and learn how to do it.
I saw that they offer an internship program..... I was thinking of trying it.... maybe for a month or two???
I took a clinic (from Hannah, too) and it's a neat little 'reminder'. No replacement for good ground work though. It does well as an attitude adjustment, and helps to build trust. Gives you chills the first time you do it, too. If you can take a clinic or internship from Hannah & Bobby, DO IT. They're good people. ;)
