Oh my, that seems like a crazy amount of snow for my brain that does not understand snow! Or who does not know it? I would not really cope with those temperatures, as I have come to love the year-round sun where I live!
Good luck with the painting, it sounds really interesting that you need to factor in the temperature! Some time that I never even though about.
Oh I will go and look! It is funny, they have tried to bring Halloween to South Africa for so many years now, and still after all the attempts it still fails, as we do not have the cultural history for it to take root. But I will check it out! Enjoy and keep well!
