(meteorobs) perseids and the full moon

Your experience is different from mine. At my high altitude location, 
the sky is black 45° from the full Moon. If I'm out of direct moonlight, 
I can see stars magnitude 3 or even dimmer over most of the sky. My 
meteor camera, which is sensitive to mag 1, catches only a few more 
meteors in a moonless year than in one with a full Moon, and my eye 
still beats the camera.

Of course, technicalities aside, I think you might be confusing what 
"fun" is to a serious meteor watcher, and what "fun" is to a bunch of 
Boy Scouts on a camping trip! <g>
