[pianotech] How does fog freeze?

[David Boyce]

The UK has had a cold December. In the West of Scotland, temperatures 
have not been rising above freezing (0C) all day. Last week, we had days 
of fog. Moisture condensed out of the freezing fog to produce fronst 
crystal formations the like of which my work colleagues and I (all in 
our 50s) agree we have never seen.

Sorry this is off-topic, but its beautiful!

Remember, this is frost, not snow.

Best wishes,

David Boyce.
