First visit to the California Coast. While driving North on Highway 1 from Big Sur, heading toward Monterey, we noticed a greenish cloud coming at us. Not knowing what we were seeing, we pulled off the road and stopped. The temperature dropped drastically and we even closed the windows. As the green cloud lifted we could see this beautiful sight off in the distance and realized we had just experienced a "fog bank". This was an unusual experience for a Mid-Westerner from Ohio. But look at the beauty.
