If you build a jump the game worrden will take it down. there was nice berms and jumps in front of the big scrub camp ground but the leveled it all out.
I hace been to hardrock also and found it ot be a very fun place to ride if you have a sport bike, but if you ride utility i would not rcomend it because the few trails they do have that are not part of the tracks are pretty challenging. If you are up to the challenge though there are very pretty coreys that you can ride around. A nother thing about hard rock is there is two tracks that is suitable for sport atv's. This is the ouback Track and the rollercoaster. On all the other tracks the catch ramp is to far away from the jump. But all and all i found that hard rock was a fun place to ride for the three times i have gone. A nother cool thing about hard rock is that when you get tired you can wothch the Dirt Bikes go of real big jumps on other tracks.
