That's true, we were in a very wet, exposed environment. We had the tent all closed up, and there were 4 people in there sucking air. Everyone was affected; when I got up, I tried rousting the girls, and they were just as brainfogged as I was.

After that little stunt, I used a tarp suspended over that tent to keep it from getting so saturated, and never had another problem like that.
