I was there on sunday with a friend. We were thinking about going out there more often, and with a shovel next time.
There were a few guys figging last year, making the big line at the back (Mark I think (the south african) wanted to do a backflip)
People were riding motorbikes in there, then a fence was constructed around the place, and gates are in place so you can't drive in there anymore. An article in the local paper that week read that it was a 'potential threat to melbourne's water supply' as they are next to the Cardinia reservoir.
I could see that the gate had been cut down in the past, and the council / melbourne water put it up again.
The jumps are still pretty good. There's quite a bit of grass growing on them, and the biggest ones were never finished, but they all have held their shape, just in need of a patch up in some areas.
The short track down the hill is a bit of a mess, and the jumps on that are pretty well rooted, but the last berm is still like it was.
I might head down this weekend.
