McFarland Park 4 miles NE of Ames, Story County, Iowa
Long: 93 deg 34 min W  Lat: 42 deg 05 min N  Elevation: ~1,040 feet
Method: Visual; paper, pencil & talking clock

During this session I had unusual difficulty differentiating between NTA's and
STA's; some meteors occurring far from the radiants, others more or less lined
up with both radiants.  The direction I was facing may have contributed to the
problem.  At McFarland Park I am very limited as to which directions I can face
with the sky glow over Ames in the SW affecting the SW sky up to 40+ degrees
many nights.  I cannot face any direction in the half circle SE > S > SW > W >
NW because too much of the sky is affected by the lights of Ames.

07:50-08:50; 30 degrees F; wind North 7 mph; mostly clear; 5% cloud cover;
