I just got back from the thing at North Ryde. It was not all that hard to get there, even if I am not used to peak hour traffic. The great thing about traffic in Sydney is that it usually does actually move, and does actually move fairly well. As much as you complain about it Sydney traffic is not really that bad.
I have booked my trip. I will post the information on things soon. It is all booked and paid for. Stay Tuned.
