              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
I thought we would be able to open tonight but no such luck with the smoke. Humidity was over 50% all night and the haze was so thick that you couldn't even see down into the basin. The smoke didn't life even after the wind shifted.
No problems tonight.
