Don't put on your pajamas on October 3rd, instead get out into the night and take in the art of Scotiabank Nuit Blanche. The "free-all night contemporary art thing" which begins at 6:55 pm and lasts until sunrise.
Sometimes thought provoking, sometimes stunning and sometimes just downright strange, contemporary art is in the eye of the beholder as Toronto becomes an art gallery. You can see my Nuit Blanche experience and photos here.
