In another lifetime my family & some friends were into tootling around the fire trails in our Land-Rovers. We adhered to the 4x4 Code of Practise & were careful to not damage the fragile sandstone track system. We were not popular with the bush walkers but they had no real complaint that they could level at us. Enter the late 1970's craze of the cheap, brightly coloured Japanese 2 stroke, trail bikes. Every kid & kid at heart who lived in the mountains had one. You could here the "Ring ding ding,,blatt blatt, crackle, for miles around. They tore the guts out of the sandstone hills & gave the Nat. Pks the excuse they needed to close the tracks & put up locked gates. No one allowed in except walkers of course. Oh, & the kids on bikes just rode around the gates & carried on. They're still closed & a colleague in the Volunteer Bush Fire Brigade told me that without the 4x4 enthusiasts doing a bit of track maintenance, & driving responsibly they can't get the fire trucks in. I still hate 2 strokes today can't stand the bloody things. So,,one group ruins it for everybody....rant over.
