Maybe you hadn't noticed, but SAU NSW includes the whole of the state, not just Sydney alone.
Those of us who live outside breathe actual air still had to drive an hour to get to the Central Coast, alot of those who came from country areas had to drive even longer, but I for one would have thought long and hard about going if I'd had to navigate through Sydney, and try and stay out of the way of the thousands of police that are out looking for modified cars.
One thing I did notice was that I didn't see a single police car on my way down, and only 1 bike on my way back, whereas in Sydney, they probably would have been sitting at the gates.
Well done to all the organisers though, it was the first car show I've been to, and I shall be going again.
Hell, if you require help in organisation next year, or for others, give me a yell. I'm well experienced in organising events.
