Brisket would not be something I would do over an open campfire, not saying it can't be done. I have always wanted to try steaks placed directly on wood embers. How about a chicken hung from a string off to one side of the fire and give it a twist every so often so it rotates, this is how it was done way back when. Just make sure to pack some tube steaks.
Let us have a drink and by God lets us not think about the things we ain't never going to know about.
