Doing the Dakar with Robby in the Hummer was one the highlights of my career. I remember the Iquique stage in Chile. I knew that the big dunes—1,000 meters high—were coming. Once we crossed the top, it was like the biggest first hill on a rollercoaster. It was scary, but Robby didn't hesitate. He went wide open all the way down to the ocean, where the bivouac was located. I think we hit 136 mph. Unbelievable.
