The village of Nimbin is beginning to get ready for its fifteenth annual MardiGrass, the cannabis law reform rally and gathering which swallows the village every first weekend in May. âUntil we are no longer criminalsâ, says Michael Balderstone, spokesperson for the MOB (MardiGrass Organising Body!) âThatâs the promise we made to ourselves and it looks like we might be doing it for a few years yet, though if Rudd replaces Howard at least the Federal reefer madness campaign might diminish.â
