Frost on a leaf

A visit to the Lodge again to get out anything that needs PAT tested and put away some things.  We are now entering our quiet/maintenance period.  On the way, Clickychick stopped to take shots of the mist in the Eden Valley.  I was too lazy.  Further along the road the mist hid any scenery so I was on the lookout for a blip.

As I got out of the car I noticed this leaf, it stood out because it was the only one with frost, the others were wet.  The trees and grass had frost.
