Well, it looks like lots of you noticed. From what I can tell, it is just the culture....they have always done it that way and it has always worked just fine in their minds. I too envy their lifestyle in many ways. Those feelings are part of the reason I have always burned wood. If I had been born in a different place or a different time where this was the lifestyle, I think I would have been very happy, and I think I would have been good at it.
