This weekend, Red Bull Billy Cart got underway. After months working with Red Bull on the event, it was great to see everything from giant underpants and a flying thong to a miniature replica of the Delorean from back to the future hurtling down the hill at Centennial Park. The carts were exceptional. Another great event put on by the Red Bull team and a great day had by all. Enjoy a little wrap up video of the day below.
