'...you couldn't cook something as large as a whole hog this way could you?'

I've seen hogs that weighed 600 lbs.... so, I don't think so. I am assuming you mean for a party or something, otherwise, why....... ?

Most people in a survival situation, if they can catch anything at all, will be catching small game (sometimes, VERY small game... like grasshoppers and grubs). This method would work for birds, fish and tiny livestock. One of it's advantages is that you don't have to sit there and keep adjusting it, like you would with spit cooking. You can be building your shelter or checking your transpiration bags while dinner cooks.
