Foggy.
Very, Very foggy.
I left the house 30 minute early because I needed to get into the office to run a very important program for a project we're doing.
I make my way through the foggy weather (1/4th mile visibility), wiping my glasses off every block. Finally make it in, shower, and get over to the office.
Find a email stating that the project has been put on hold and I didnt have to come in early. Grr
It was foggy.

BTW, has anyone else noticed that in extreme fog, sometimes you have more lights turned On on your bike, then some cars have on?
