Where Did the Tops of the Buildings Go?

Sort of a random thought I guess…

Today, as I was driving to work, the top of the city was missing. It was really foggy and the taller buildings just kind of went up and disappeared into the mist. Whenever this foggy sky thing occurs, I always think how there is no way in hell I would go up to those top floors. The way I figure it, if I can’t see it, it’s not actually there. Or, it’s there, but once you hit the mist, you are seriously taking your chances on going up into some strange Twilight-Zonish world of fog. Basically, it freaks me the fuck out to see this particular phenomenon, and I don’t know why.
