Good stuff Jason. Beach tracks like that help tune your sand riding skills! I know its a bit of a lottery, but were you not tempted to get out of the 4wd ruts and try the beach itself?
Good to see the twin cylinder BM out there. How much suspension travel did Rooney manage to engineer into the rear suspension? My brother and I built up a similar 1000cc BMW for the early Aust. safaris held in 1985 and 86.
