Related to my theme in a way is the Improv Toronto Events such as the No Pants Subway Ride ( which u can see in the link below). Like Subway sketching, the no pants subway ride could perhaps be a way of artistic expression in the public space. I was not involved in the No Pants Subway Ride but I have seen it happen during one of my subway sketchin days. For those who are thinking "omg dude really? No pants on in a public space?". Yep just check the youtube link / the Improv Toronto website for more info.
