I make a distinction between memorizing and rehearsing. Memorizing and repeating is much more difficult for me (and I assume for others). Put I have no problem with rehearsing. I'm doing a workshop on RVing at 4C Camp for Adults this summer. It needs to fit the required time-frame and still allow for unexpected questions. But as I said in a comment on another of your posts: it gets easier each time! Another good post, as usual.
