I was travelling from Sacramento to Yosemite on Christmas day, but was trapped in traffic. When I got there, sunset was already gone, which is what I planned to shoot. I was very sad at that moment because that was my only chance in this trip to shoot sunset at Tunnel View. But a few minutes later, I noticed the light path formed by the cars was a great leading line to the valley during the blue hour, and a little bit fog was just formed above the road which made it even better.
