I was just curious about these "private" workshops, not the ones put on by EC or the publishing companies. It is my understanding that they are put on by former students? I had just never heard of this before and was wondering who these people are and how much they are charging for their workshops. When I was still a student, there was a student who bought and rented a hospital bed, IV pump, and loads of other supplies and equipment and would invite people there to practice with him. He referred to this as a "workshop" which I thought was pretty funny.
I took EC's workshop too. I recommend taking theirs to everyone, since they are the actual horse. :)
