I recall a recent thread where the quality of Cowboy lump charcoal came into question.
I stated that I had seen flooring scraps in the Cowboy coals and at least one person disagreed with my assessment.
Just this weekend I opened an old bag of Cowboy that I had to cook some hamburgers & hotdogs. (I would never use this stuff in my smoker again).
As I poured the charcoal into my chimney starter I once again found a piece of flooring scrap, so my son and I took a couple pictures.
In this photo you can see clearly the grooves in the "down side" of the flooring board.
This one shows the tongue side of the tounge and groove of a flooring board.
This final picture shows the groove side.
Take if for what it's worth. I just thought I should bring this to the attention of anyone who is considering Cowboy lump charcoal.
