              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Candace did my evening checkout for me as I was going to be a little late on arriving on site due to a Doctors appointment.
It was foggy and light snow flurries when I arrived a little after 6PM, so not much to do.  My observer had already taken cals and left a phone number to call if conditions improved.
For most of the night it was cloudy with a few brief patched of clearer sky but the humidity remained high for the entire night.  We never opened and gave up at 05:20.
Just a dusting of snow on site tonight
