Evening cloudiness made this an iffy night, but clearing skies were  
expected into the overnight.  I drove to Bootland Farm, and then  
waited for the clouds to part (taking a short nap).  When I woke up at  
11pm EDT, the northern sky was almost entirely clear, so I signed-on  
shortly after and I was able to observe for over two hours.  I kept my  
field of view to the north, to keep an eye for Draconids.

During that time, I logged a total of 28 meteors (which breaks down to  
17 sporadics, 7 South Taurids, 3 Delta Aurigids and 1 Draconid).  No  
meteors really stood out though ;)

On my way out in the morning, I startled a single wild turkey that was  
roaming around the entrance way.

OBSERVING PERIODS: 0 = none seen; / = shower not observed

Note: The first column (Period UT) refers to the observed periods, in  
Universal Time. The second column (TEFF) is the effective observing  
time, it is minutes/60. The column (LM) is the average naked eye  
limiting magnitude, determined by the triangle star counts method. All  
following columns indicate the number of meteors for each shower  
observed.

MAGNITUDE DISTRIBUTIONS:

SPO___4___3___7___3_____+3.53
STA___1___2___4___0_____+3.43
DAU___2___1___0___0_____+2.33

Note: Magnitude -8 is comparable to a quarter moon, magnitude -4 with  
the planet Venus, magnitude -1 with the brightest star Sirius,  
magnitude +2 to +3 with most average naked eye stars and magnitude +6  
to +7 are the faintest stars the naked eye can see under typical dark  
conditions. A meteor of at least magnitude -3 is considered a fireball  
(IMO definition). The above table contains the magnitudes from all  
observed meteors, and the average (last column) for showers.
