Not really sure if that’s what these stacks are for. Mauro and I came across them on our way back to the car Sunday. This is on Yonge St. just north of the Air Canada Centre. For those not from Toronto, the ACC is the building where the Toronto Maple Leafs lose at hockey every week. As for the photo, I dialled up the contrast and played with the colour and lighting. Some might not like the effect, but I think it works.
