I still haven't seen the foggy morning or night in London, which I'm still waiting to see. It might not be the thing I imagined while reading the stories, but just a wish!
On a different note: fog and mist are also my favorites, especially when those cover the lakes while you are in a boat! I had terrific experiences regarding fog while I traveled inside the world's largest mangrove forest, the Sundarbans. I thought the water vapor covered the earth, in the chilly morning, while unknown birds chirping from the forest!
Thanks for exploring my words. I would love to read a foggy night travel story of yours in the upcoming time, whenever you write it. Best regards.
