I've been to several and hope to attend more. Do yourself a favor ( and the instructor.) Leave what you think is your knowledge at the door. I like to evaluate a course from the perspective of a complete novice. Sometimes one instructor will have a natural gift or different way of teaching something. If I'm half attentive to a familiar subject, I miss the unfamiliar. Of course, if you have something valid to contribute do so. A good instructor is one who learns from, or molds students to 'raise the bar' of the subject. Everyone has a persona. Peter at Reevis Mountain School likes to discuss reincarnation around the fire. Of course, this is AFTER Peter teaches everyone to make a friction fire. Now if somebody started talking about Area 51 during a navigation class I'd feel probed, violated and abducted. <img src="/images/graemlins/blush.gif" alt="" />
