After pulling an all-nighter on August 11/12, I didn't feel up to the same 
tonight. I did a casual watch at the end of twilight and saw quite a few 
relatively long and faint Perseids, but decided to focus my attention on the 
predawn hours. I ended up counting for 2 hours between 0926 and 1130 UT. I 
saw 214 total meteors including 153 Perseids. Skies were awesome, so there 
were a lot of faint meteors. As others have noted, the Kappa Cygnids were 
quite active with 6 meteors. My brightest meteor was a -3 Perseid.

This was the first time I've gotten a good view of this Perseid peak timing 
(1995-Moon, 1999-clouds, 2003-Moon again). While the predawn hours of August 
12 should be even better for my location next year, the fact is that this 
year I was able to break 100 meteors/hour on two consecutive mornings. I 
don't think I've done that before; obviously, excellent sky conditions (no 
nearby forest fires this year!) played a big part. It would be nice to get 
this kind of sky during the Geminids once in a while...
