The Carousel offers all photographer the opportunity to pan without interference from fences, obstructions, or other people. It offer an expansive 180+ degree sweep with a background of forest.
I used a 200 mm lens on a monopod to pan these images. I was totally unsuccessful at less then 1/60th of a second but more successful at 1/125. Any faster shutter, and you start seeing more discrete objects in your photograph. The race cars appear to be traveling in excess of 200 MPH at the entrance to the Carousel.
The image was captured at the Carousel (2-2 on map).
