I've probably ate a truck bed full of those. Never smoked one though. When I was 19 or 20 me and buddy of mine rented a little house together and pilfered all the arm roast his Mom and Dad would get plus alot of other steaks. They owned a big cattle farm. We didn't have any money, but we had free meat and a Weber kettle and ate like kings most of the time. We would cook these just like a big steak and have a two plate steak dinner. One for the "steak" and one for baked taters and a vegetable if we got around to it.
Excellent meal, brings back memories of steak and beer night which 3 of us were "always" gonna do at least once a week before wives and kids.
