Fortunately where the quarry is noise won't be a problem. There is a fully operational gravel crusher going full tilt. I recall reading somewhere the land was to be gifted to the Penrith community by the quarry owners ( CSR, i think ) for recreation purposes. We don't need MA to buy this land, we already own it, what we need is the local council to green light a section of it for a off road park. More dirt bikes would travel straight through Penrith, heading another 90 minutes west to access riding land ( mostly illegal on a MX bike ) than anywhere else in Australia. Like Slakewell said, it would take SFA to build this. Penrith has an International Regatta centre ( olympics were held here ) and a world class whitewater facility on this land. I think it would make sense for the community to capture these dirt riders. Nowra, Mt Kembla, Oakdale and Clarence all have off road tracks. You could fit all of those towns into Penrith, no problem.
