Dunedin is arguably chronologically the first city in the world to host any GMM event. Named '4:20 Extreme', local participants climb the famous Baldwin Street to meet at the top by 4:20 am. Locally J-Day coincides with The University of Otago Capping Parade, in which a multitude of ceremony-attending graduates parade down the main street on their way to the Town Hall ceremony, and also the University Hall Parade, in which University of Otago dormitory-student decorated themed floats parade down the main street, stopping in the Octagon typically armed with many water balloons, and collectively shouting chants of dormitory-specific pride.
