I had a chance to attend the IndyCar Grand Prix at Sonoma Raceway in California last weekend.It was the first time I had been there.It is a very nice facility to take photos.
Here's a few photos from the weekend.C&C is always welcome.All photos were taken with a 5D mark III and either a Canon EF 70-200mm f2.8 II or a Sigma 120-300mm f2.8 sport w/Canon 1.4x III teleconverter.
You can see the entire set on my flickr if your interested.Here's a link.

Marco Andretti and EJ Viso.Even in the pits they seem to be racing.
