If it is any relevance to the quality of the food that is cooked in the ground, I can remember when I was much younger and we used to go to the beach and spend a couple of nights (when you could actually do that) and we used to get all kinds of sea food (lobster,fish, crabs, and shrimp and cook them that way. It always came out great. Never over cooked, never under cooked and the taste was always the best. I think you may be on to something...sabre11004...
