This is my 3rd time at this location. First time I made a panorama of the entire area since the view is great. At that time I already noticed the road that surrounds the city and I thought it would be good to capture car trails on it to give the city a bit of an edge. The 2nd time I was here the sky was uninteresting. This time it was great, a lot of clouds and enough contrast and detail. I waited until the sun goes down and city lights go on. I took the long exposure for the sky and then I was shooting for the car trails. I took some 10 shots but the car trails was not covering enough road. But, I got enough coverage at my last attempt :). In post process I combined the two exposures and this is the end result.
