Rained heavily overnight yet again and the day is grey and wet. I'm beginning to feel a slight touch of cabin fever and it's not even winter yet, LOL, even though snow fell a few days ago in the mountains and we might get snow/frost later this week. The snowy peaks looked so beautiful from the city.
