I was waiting in Tekapo with my son for my wife to arrive. We had just finished spending the day shooting the Loon Balloons from Google X, and we were going to meet Tina and the girls in Tekapo. Since they were arriving after sunset, I wanted to find a good place to watch the sun go down. I could not decide between Lake Tekapo and Lake Pukaki, which are very close together. So, in between the two, I saw this fog rolling in and decided to stop and take this photo.
