In Bangkok we never get any close to the ground up to the face fog at all. As you can see they do get some of that in Pennsylvania. Once I flew into Pittsburgh and my father came to pick me up at the airport. It was late at night and the fog was so thick that we could not see more than three feet in front of the truck, yet my dad continued to drive 55 miles per hour. I suggested that it was dangerous and that he needed to slow down, at which he responded with "Oh, I can see the stripes on the side of the road." I'm sure he was referring to the stripes beside us, not the ones more than three feet in front of us. If anything should happen onto the road, a deer, a person, or anything at all, we were sure to hit it. I will never forget the words that came out of his mouth immediately after he told me he could see the stripes, "Oh! Where did they go?"
