Ig, other than wasting a tremendous amount of heat and potential flavor-
enriching fat-smoke, what's so great about that?

It's just a brazier with a rotisserie, and a wasteful "non-barbequer's
intuition" way to roast a shoat.

Close it in, and you build half the fire, capture all of the smoke, and
produce a superior end product.
