Look what I found today: a Zombie Survival Challenge that's run at Muriwai (not far from Auckland). It looks very cool: you make up teams of four and they arm you with Airsoft guns. The instructor's a guy who used to be in our air force. I bet astrogirl2 would be up to it if she lived here.
imhilien, maybe an idea for a Stella Nova outing? It's pretty new; it only started last month.
