                  ------------- ACTIVITY LOG --------------
 1st half Observing Specialist: J.Dembicky
 Some clouds started the night with what appeared to be more looming in
 the West.  Clouds finally looked a bit too threatening around 22:10 so I
 decided it prudent to close (Sloan also was closing at this time).
 2nd half Observing Specialist: R.McMillan
 Second half had rain, sleet, thunder, lightning, and high humidity.
