I was driving to my usual parking spot at the tidal basin paddle boats parking lot when I saw this. I quickly stopped even before I could see if anyone was behind me (luckily there wasn’t) and just stared at this scene. The fog simplified everything so much that it really became about the lines and shape of the trees and the monument. I immediately parked and ran back. I couldn’t let the fog go away. I think it presents a sort of creepy, Halloween-y mood, don’t you think?
