Good vid but a bit strange, why did he not leave a low gear in and just drag the rear? If you are not on good rubber why even brake on that dust! Bet he absolutely sh*t it towards the last hump!
I had my little traillie pop out of gear on something like this. Oddly enough my buddy was pissing himself when I got to the bottom too. So who reckons the laughing was proportional to the tightness of your mans sphincter?
