Smoking Multiple Pieces of Meat

I always feel the need to fill my smoker with meat just so the heat, smoke, and time won’t be wasted. Maybe this is my frugal side coming out, or perhaps it’s just an excuse to make lots of succulent barbecue, but it just makes sense to me not to waste a grate when it could be the home for another rack of ribs or a nice plump Pork butt or brisket.
