There were some questions about what freezing fog actual looks like.
These pictures weren't taken the same day, but that isn't really important.
This first one shows you some of the ice crystals up-close. Granted, not the best, but the best I can do when the sun has yet to come up.
The picture of the tower might need some explanation.
You can't really see the guy wires, what you are seeing is the ice crystals that have built up over about two days. This was the first real sunny day, so the frost started to melt and come off in chunks. Don't worry, not damaging chunks, more like snow when the sun is out. It still took about two days for the entire system to be clear of frost.
