I would be more worried about embers falling out onto a combustible surface (if that's what it is). Up here it is against the law to have a charcoal grill on a wooden deck, it must be gas. Some communities go so far as to say they must be hard piped gas.
Am I tough? Am I strong? Am I hard-core? Absolutely.
Did I whimper with pathetic delight when I sank my teeth into my first brisket? You betcha.
