I highly recomend one of those books that lists septs & their accociated clans along with a concise information on clan histories. When someone comes up to your booth ask if they know their clan. If "no" then show them how to use the books. The greatest pleasure for me is watching teens devour the information in the books & ask questions. I had one young fellow (about 14) who had never heard of William Wallace. And he was a Wallace! The boy left with enormus (sp) pride ...... and a hundred questions for mom & dad
