Looks like the full moon in August is Aug 29th.

I've never been to one, only seen the pictures. They look absolutely horrible to me.

My advice is to drink bottled beer, bottled water, and stay away from drugs. Yeah yeah, I know they can rebottle/seal beer and water, but at least you're taking an extra step to be careful.

Avoid power lines and water. Avoid flammable liquids and open flame. Be mindful of your valuables. Don't take strangers back to your room.
