A lot of great stuff. For only $485 I can camp and drive my own vehicle around a small dirt course too. I'm in!
You're obviously a seasoned pro having never been to said event but professing 110% knowledge about the event and the psyche of each and every attendee and vendor. Start your own Expo, force everyone to drive only their vetted/seasoned vehicles to the show and charge just $450, include your autograph.
The bulk of those classes and presentations are free to those with a simple day pass. Of course you invented real overlanding so you knew that.
