Entry to San Francisco:
I went to Bernal Heights park on one evening. I saw this beautful criss crossing of freeways 101 and 280 along with car trails when I was leaving. Fortunately my camera was with me. It is a single picture taken with Canon 5D Mark III, with EF 70-200 F/4 L IS lens, at 200 mm, F/8, 25 sec. Imported / processed raw in LR.
