It was a great spectacle last year. It is something you don't get to do that often. The venue is close to melbourne, friends and family
can come along. That out weighs the session or two you may miss for the event.
You had a few prangs last year, that slowed the event down. I don't see why you couldn't get through the groups quicker without
that issue. Knowing what you do now, parking (lack of), sign-in (30deg, line out the door) should be much better.
