Season the roasts with Lane's Brisket Rub.
Cook the roasts for 2 hours in the smoke.
Move the roasts to a full size pan with the broth, onion, and garlic.
Cover the pan and set it in the smoker.
Adjust the smoker to 350 degrees and cook the meat until it's ready to pull (additional 4 hours or more).
Mix the meat with the juices and build the taco of your dreams.
