They always say it's not, but there's always guys taping it in the back of the room....get there early for a spot.
Last year's cd had (most of) the presentations (powerpoint) and (again, most of) the audios of the presentation. It was semihelpful for most of the presentations, but for things where they're drawing on a white board or demonstrating something (Gait's shooting clinic) it was a poor substitute.
Edit: It looks like they upped the price and also that they're making videos (on DVD) of the live field demonstration....
