FWIW, there's some good deals on Rhino dart hunts in KZN at the moment as they all now all have to be chipped by law and the landowners would prefer to sell the dart hunts rather than do it themselves. One particular deal I've been offered is buy one get one free!.....which although it sounds a bit silly is a good idea. While you're paying for a chopper (etc) for one you might as well use it for two.
