I know about a pack crossing the coat hanger. Back in the 70's the gumbient introduced a toll for motorbikes (previously free). About 1000 bikes turned up. Each bike stopped to pay the toll. Stopped the bike, took off the gloves, produced a $50 for the (I think ) 5 cent toll, put change in pocket, put on gloves, started bike and rode off. Followed 999 times. They dropped the toll.
The Nowra ride is along a route I travel often. Hope they keep up!!
Cheers
