                 ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Persistent light snow, rain, sleet, and fog during the evening, with
 heavy snow accumulation forecast to begin at midnight.  One observer
 wanted to practice working with the instrument, so I set her up for
 cals; otherwise, I told observers to go home.  I stuck around long
 enough for a second set of instrument fills and then scarpered
 before I could get stuck on site.
