Three hours work later... the trail has been re-directed over boardwalk (or corduroy) to the left of shot (yeah - where everyone is standing to admire it), and the area on the right mulched.
See how this looked before and during the work.
Great job one and all! I would have come myself to pitch in but was racing at Ourimbah. Made sure that I contacted the ranger though to give some support of the whole thing.
Just wondering, any interesting run ins with those people silly (selfish) enough to be riding the Dam even though it's closed?
