last time i was at kambah was for the meca round last year that was rained out

couldnt make it back for the re-run for work comitments...
but somone tipped oil all over the track the night before for what looked like doing burnouts on the back loop before you come back onto the straight. i hope this didnt cause any long running damage to the circuit?
track was a nice track to drive on from my previous days practice, a little dusty, but what can you expect from a parking lot track - after a good sweep/blow it would improve heaps i'm sure
