Great shots! I love the view from above the clouds.

I have experienced really think fog. I was a relatively inexperienced driver and I was traveling down the highway and suddenly the fog got so think that I had to downshift all the way back to second or third gear. I couldn't really see the road, just faint reflections from the siderailing and just a bit of the red lights on the back of the car in front. And the car I was driving had really good fog lights. It was really stressful but I still didn't relinquish the driver's seat to the much more experienced driver that was traveling with me but I kept listing to the pointers he was giving me.
