we've got the same damage to fix tomorrow actually in the Beachport sand dunes after idiots did heaps of damage on the Melbourne cup "weekend". It was so bad that the local coppers want to put surveilance cameras in there. Much of it was done by paddle tyred bikes, but the fencing obviously damaged by "cars". Its plain stupidity, because national parks are looking to close parts of the sand dunes, and that will just hurt everyone.
