Yeah man, that Bohle place I mentioned is pretty easy to find. And it's pretty fun to ride.. heaps of different dirt tracks and jumps.. not exactly a "motoX park" but after years of dudes riding out there it may as well be..
Get on Woolcock street and drive towards Ingham, it turns into the bruce Highway. Not far out of town, you'll go over a bridge and if you look left you'll notice a whole bunch of tracks and dirt roads through the grassland and scrub. At the end of the bridge is an intersection where Ingham road meets the highway. On the left you'll see a fire station.. turn left at the lights and then take the first left after that (its only about 30 meters from the lights) and its a really shitty road with a million massive pot holes.
Just drive along and it will open up after about 200 meters.. just park anywhere, if you go on a weekend you'll see heaps of people out there riding.
There's another place where people do a lot of riding and trashing of bombed out cars, known as "the savannah".. but it's all dried up swamp land and mangrove salt pans so if you value your bike at all, i wouldnt ride there, your bike will just rust to pieces in no time.
Good luck! let me know if you have trouble finding the other place I mentioned...
Id say lets meet up and go for a ride, but Im going overseas in 3 weeks and Ive packed up my trailer, so Ive got no way of getting me and my bike out there!
