It seems as though many people think Parelli = DVDs, books, special expensive equipment, and that all this is wrapped up in a promise for "success"??? But I don't believe that's entirely true. The Parelli System has real, live teachers, who DO think for themselves-- they're not carbon copies, at least in my experience--and they expect you to think things out. They are crucial to the program. I never heard of anyone trying to train a horse using ONLY DVDs and lesson plans! You could easily find yourself confusing your horse.
Just wanted to throw that in, to be fair. (I'm not a Parelli student, also can't afford it, but I go to their clinics, and the teachers are generous in their help. If you didn't know, you'd think they weren't Parelli...)
