We bailed after a while too, there's just only so much of it i can take. We noticed that a lot of the stops in the parade were due to having to let east/west streetcars through periodically.
Overall there was a great vibe in the area all weekend. Church Street looked great... though i was disappointed that you couldn't see into Cawthra Park for all the hoarding put up.
Was it always like this? I found it totally ridiculous that they let streetcars through. Hello? Road closures? I left after 1.5hrs.
