Couple of weird hoar frost things I've seen once and never again, and both times without a camera. One morning I went down to the front door, and found that I'd left the little cover off the keyhole, and frost had grown in to the house, about half an inch long or more. And another time, after a wet spell, a brick wall had grown curly hair of frost along the top as the water expanded from the pores.

I need a good frost. Without it, I don't get set up for the year!
