I'm in the anti-cowboy club. My last bag was garbage. The photos of the tongue and groove are proof. If this ever had stain and sealer on it, maybe all that stuff came off on the charcoal making process, but why would we buy that stuff when there are other options? As I said before, I'd just cook on my Genesis if my only charcoal option was cowboy. I don't like the idea of construction scraps as raw material for charcoal.
Mike - the random sizes are a challenge. I started breaking up the bigger pieces. I dump about a chimney's worth, and sort thru it, and anything that is longer than my palm is wide, I snap in half before I put in the chimney. I've really been enjoying my lump charcoal cooks since I started the sorting and breaking process. Once could also use a hammer or hatchet to break the stuff up if need be.
