              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
There was one word for the night: wet
We had clouds, fog, rain, sleet (I think), more clouds, some more rain, then maybe some more sleet, and I think we are just back to fog now. I mostly huddled in the dome and did filter work.  I can't feel my toes...
Here's a little ditty about it all:
You're as cold as ice
You're willing to sacrifice blood flow
They socks don't suffice
Someday you'll pay the price, l'il toe
