I planned this trip to the sand dunes around the full moon, so that I could do some night riding. While out there, I found a high spot, and set up the camera and tripod. I set the shutter to bulb, and opened the shutter. Then I got on my ATV, drove out to the middle with the lights off. When I got to the center of the frame, I turned on the lights, held the brake just enough to illuminate the brake lights, and started riding in a circle, slowly arcing outward. I used the tire marks from the previous arc to help space my current arc, so they would be evenly spaced. When I felt like I had filled the frame, I rode out of the shot, turned off the lights, and rode back to my equipment and closed the shutter.
