chet: what they hey kind o' monster gas grill you got, dude??? I ain't seen the gas grill that can hold even a suckling pig... and unless you got a 250 or bigger, forget about the cs.
no... you gonna have to do like them good ole boys do in eastern NC: get you about 60 cinder blocks, stack em in a rectangle about 4 by 6 by three courses high... or better yet, just dig a pit in the ground... find a big metal screen to lay that bad boy on... and get you a couple weber kettles to burn down some wood, and take a sturdy shovel and feed coals under that hog, lay a big sheet of cardboard over the pig (take apart a big ole refrigerator or air conditioner box)... and tend it for about 12-14 hours... start it on its back and flip it over halfway through... and you will be the king!!!
