Look we dont want any violence, or even the suggestion of, so make some official contact with Rocky Trail and your get in the ear of you local MTB Club or try one of the event organisers in the Northern NSW / SE QLD area. Refusenix is a name that springs to mind for the Northern NSW region, but I know RT travel the world organising events... SE QLD is a pretty nice place to ride.Can someone please get something like this happening in south east queensland! You punch a small child in the throat to have access to this kind of competition.
