A couple of weeks ago, I drove along The Desert Road. Once I drove this road in such a fog, I couldn't see my car's bonnet (hood, if you're American). Another time, the rain was so bad, I again couldn't see the bonnet. So scary when you're driving an awful road for about 40 minutes. I won't travel The Desert Road in the winter.
But I love looking over to Mt Ruapehu which stood in for Mt Doom in the movie "The Lord of the Rings".
