Starry Night on Foothills Parkway

I took my family up to Foothills Parkway tonight to star gaze and maybe see some of the fireworks at Booms Day in Knoxville. The fire works were too far away and were quite small but the stars were out in all of their glory. I shot this 30 second exposure with my camera on a tripod and lucked out in catching some traffic as it zoomed by. I was shooting with a 17mm wide angle at f-3.5 at ISO 1000. My white balance was set for  tungsten light to give the sky a blue color. It was a good clear night with a little bit of a chill in the air.
