Now that I know that I'm not the only backwoodsy person on this forum, I shall ask:
Have any of you used your smoker for hide tanning? It seems like it would work really well- just make a "tipi" of the hide around the smoker. The contained burn would be a lot less trouble than maintaining a smouldering brush pile, and no worries about the hide falling onto the fire if one of the support sticks gives way.
