It's an end of an era in Oturehua in Central Otago this weekend as motorcycle enthusiasts gather for the 40th and final Brass Monkey rally. The first rally -- named so because the location was considered 'cold enough to freeze the balls off a brass monkey -- took place in 1980 and attracted 300 riders. They're expecting 3000 this weekend. Professional director, writer and Radio New Zealand Board of Governors member Mike O'Donnell is attending his 24th Brass Monkey rally this year. He joins the show from Oturehua.
