NOTE: 

I forgot to note before that when we were driving around Coober Pedy we saw a guy cycling along the road, approximately 100kms out of Coober Pedy and travelling North. For the life of us we couldnt understand what or why he would be doing that. He had what looked like sleeping gear, maybe a swag and a sleeping bag on the side of his bike and he was powering along the road. All we could think of was the shear force of the wind behind the road trains that we could feel in the car and what that would do to him on a little bike. Anyway, when we were almost to Alice Springs, we saw this guy again! We still have no idea why he is doing it but we hope he gets there safely..... the crazy mofo!
