No idea Nick, I have only been once and it cost $80, including a mate. (pit crew) I believe I would have got 6 runs in on the Saturday if my mate didn't sook about it being too cold. You can see by the YouTube vids the camera was shaking. Limp.
Duncan, I would drive up for sure but I would need a boot full of e85 jerry cans, no room for sleeping. lol.
