It's white with frost this morning. The temperature is down to a chilly 27° F and everywhere looks so pretty. I love it. However, the past two mornings the Napa Valley experienced very heavy fog. Not the marine fog (advection fog) that the nearby Pacific Ocean bestows upon the Napa Valley in the summer months, thus ensuring that Vitis vinifera thrives here, but radiation fog; damp, dense and with rather poor visibility. Or 'proper' fog as I call it when speaking with my family about the vagaries of Bay Area weather to better differentiate it from the marine layer. I love foggy mornings too. Morning weather like today's evokes childhood memories of walking to school cloaked in a thick fog - alone, but surrounded in the gloom by other neighbourhood kids heading in the same direction as me. I really looked forward to those rare mornings. Yes, rare. Contrary to most American's beliefs, the English do not live in a constant pea soup. Now, instead of school children appearing from out of the murk, it is the apparitions of leafless trees, skeletal vines and the yellow hint of the burgeoning mustard crop that loom in the near, but hidden, distance. And I'm not walking to St. Augustines anymore, I am driving to TWWIAGE.
