[pianotech] How does fog freeze?

[Terry Beckingham]

Actually fog that results in  hoar frost is not frozen until it lands on or 
condenses on objects like the trees shown by David. There is, however, ice 
fog, that is composed of very minute particles that are already frozen. Ice 
fog does  no create hoar frost. It occurs at considerably colder 
temperatures. It is fairly common up here in the wilds of Northern 
Manitoba. (I was a meteorological tech in a former life).

Happy holidays to all.
