RDU = Rockets Downunder , members off this site meet up once a year in a preordained place, this year being Torquay Victoria 17-18-19 Oct, some members are extending that and heading to Tassie for another 5 days , here's a couple links to the relevant threads

People coming from all over the place and meeting up on the way to roll in together ,
there's a link somewhere to the accomodation but i cant find it right now , i have a 4 berth cabin booked already , Cusso_Ken has dibs on one bunk if you decide to head to RDU im sure we can find a spare bunk , just means you will have to pay the Extra per they will charge and buy me a few rounds
