On a side note - camp fire. Several years ago, at a camp site, dude started a fire to cook over. He's a doctor. A Gen Prac doctor, and relation. He was complaining about the smoke blowing right where they were going to sit.

I said "Bet you started the fire on that side, didn't you?" Yes. I said "smoke always goes to the side you start the fire on." He was amazed, this doctor. Said I never knew that! How'd you know that? In boy scouts? I could not contain myself............."no, Dr. It really has to do with the way the wind is blowing."
