Oh tell me about it. I don't know if it's a CA thing or what. But your right, since the meat is prime rib, it's like the butcher carves out the meat with an xacto knive or something.
I smoked 3 racks of beef ribs on Sunday, and it was a big disapointment. Every bite that seemed to be a succulent piece of meat turned out to be a tooth-shattering bone.
I think you have to find a butcher and tell him that you plan to smoke them, and he'll see to it that you get some meat on the bones.
But whatever you do, don't buy the pre-packed bones, unless it's for your dog.
I'm ashamed that I soiled the sanctity of my beloved WSM with them filthy bones.
