I think that the rider on the left in this video is quite scared whereas the person on the right is enjoying the thrill of the ride and the adrenalin rush it is bringing. The only thing that I think could be going through their heads are: “AAAAAAAAAAAAAAAAAAAAHHHHHHHHH! Aah aaha aah!” And “wooooooooooo hoooooooooooooo!” I think that I would enjoy that ride and hope to go on it if I get to go to the Adelaide show this year. The one on the left doesn’t seem to do anything but look up, look down, and open and close his mouth. The man on the right however, is yelling and screaming for it is so much fun through his eyes and mind. That is what I see when watch this video.
