While the 29th floor is the highest floor I have lived on, I know well what it is like when your view is completely obscured by fog. You look at your windows and see nothing but gray white, as if your windows suddenly have become frosted glass.
The residental units at the Hancock begin on the 46th floor, shooting up to the 92nd floor. I am sure they are accustomed to having their view disappear in the winter.
