Some of the better photos I got of Nuit Blanche.. They are still crap but better than nothing. First couple of hours were absolutely insane. My advice is to hit the edges of the festival at first (Gladstone, Wynchwood Barns, Fort York, etc.) and wait for the crowds to die down a bit before hitting the main portion of the festival along spadina and Queen. After 3am it dies down considerably. Got on the subway at 3am at Union, by the time it reached Dundas the train was so full that people were being left on the platform. Felt like rush hour, not the middle of the night. People were leaving in droves around then. Sure enough after crashing at a freinds place for a break for an hour or so and heading out again the crowds were a lot lighter. No line ups to enter the art pieces, etc. Way, way better.
Empty Queen Street at 5am, this was absolutely full of people 3 hours earlier. The cops were having trouble letting traffic up and down University ave. as there were too many people and they were crossing no matter what the signals said.
