A nice little night street festival on Yonge St in the Fall is Nuit Blanche. I loaded up with the Sigma 30mm f1.4 (for the dark) and went walking.
This guy was prancing around in lycra down at Yonge-Dundas Square so I had to catch him in action. It was very busy! And quite chilly, first cool night of the season really (it warmed up again after that night though). You can see all the people down the street in this shot.
