After realizing that this topic was started in December of last year, I thought I would repost my reply in hopes that it would get it going again
Hello fellow Magicians!
This is Jack's Daughter, Jen. After reading this thread I spoke with my mother, who spent the summer at magic mountain with my father and several other people, and they have a lot to share about it. If you are interested she and a few others agreed to share the experience with all of you. She worked with my father as his assistant in those days. If you would like to submit some questions, through me, I can pass them on and fill in the blanks about it.
