It's really cool to see everyone on the ice with their headlights in the dark. We're like astronauts on the moon. We all wear the same snow suit, and you can only see people's eyes. I usually wear goggles, too: At -26C, exposed skin doesn't last long. 

The view of the ice from the bridge is cool, too: You see headlamps and you see the way they're pointed. It's  super-interesting, and fun to watch. 

There's plenty of work to do and much has been accomplished, but more sleep would be nice.
