Carson City rarely gets foggy conditions. I had family in Pacifica California and remember the fog they get there almost daily. It is so thick there you can't see farther than around 3 feet in front of you at times. The kind of fog we do get in Eagle Valley during the winter is nothing compared to some places in the world but it is an interesting change. The video below is of my bicycle commute this morning.
I also hiked up Duck Hill on Saturday and here are some pictures of the fog we had that morning.
