not an urgent concern, just a wondering aloud...any thoughts or science or just simple observations, about placing a large split bark-side down on a good bed of coals? Of course, when trying to catch or get flame is a concern we like raw, rough wood on the coals - but what about when we have solid coal bed? i just dropped one in like that because it is slightly more fun to watch. When the wife asked why i did that, all i had was "because it's cool"
