If you want to drive in, you should still be able to park in ultimo or pyrmont and hoof it, especially if you get there early. It's not a long walk to the CBD.
Nice meeting you guys today. It was tough finding a clear shooting position with all the crowds. Only decent spot I found was almost directly in front of the Cenotaph shooting over the heads of two seated people.
Chris, those photos look great. That guy was floating about before 9 and also when we could wander in the centre araeas. Then a swarm of photographers literally jumpped on the guy and snapped so much of him.
