              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Come to the mountain, they said.
I'll be clear, they said.
It started out kinda clear with good seeing but clouds were rolling in by midnight. It got thick enough that I closed.  The humidity starting increasing and we received some light rain and then fog and clouds the rest of the night.
With the fog still rolling in after 5am, I called it quits.
No problems tonight.
