I drove from Burlington to White River Junction with Calef and the dog sleeping in the passenger seat. 89 was covered in such thick fog that I could not breathe. All that was visible was the white stripe on the right and the broken white line zipping past on the left. I was almost completely blind. Calef would open his eyes every now and then and tell me not to drive so fast. The dog kept on sleeping. We got home at 2:00am.
