I had the pleasure of attending a most amazing exhibit of the works of Leonardo Da Vinci. Hundreds of his original sketches are on display at the Vancouver Art Gallery. The exhibit is also free. There was a huge line at Robson Square apparently 6 hours in length. But it was not for Leonardo. It was for people waiting to get a ticket to ride the 8 storey high zip line that dangles above Robson Street. 
The red arrows are the line up for the zip line the yellow arrow is the start of the zip line. It is cool. Click on the image to see it in action.
The sad thing was that there was no real line for Leonardo’s sketches. Which a collection of 200 that is unlikely to appear anywhere again in our lifetime.
