Hi All, I met this guy Robert Burns at Geoff Lawton’s place when I did my earthworks for water harvesting course. He was a woofa . I did notice his eyes were looking not quite at me when we talked. I now realise he is partially blind. I think his Ted X speech is one of the best I have seen and I urge you to give Bob Burns 15 mins of your time. Want to  ask him to be a tour guide on our farm. Enjoy.
